Flash corrupted in Firefox, Konqueror

English Multimedia
#1

Flash isn’t working properly on my old ThinkPad R51. I have OpenSUSE 13.1 on it and the latest version of Flash available (tried both from the repository and from Adobe’s website). All Flash videos show screen corruption: the videos are reduced to half the size they should be and have some weird pink overlay on them, as seen at bottom of post or http://i.imgur.com/0Q1fGk1.jpg.

Interestingly, Chrome with PepperFlash works fine – it is only in Firefox/Konqueror/browsers that use the system plugin that the problem arises.

Has anyone experienced this before and know how to fix it or have any ideas on what might be wrong?

I don’t think this is anything to do with Konqueror or Flash because I have entered the URL you show into Konqueror running on an extremely basic Acer eMachine 520 and everything comes up full screen without any problems at all.

#3

Same result here, neither KHTML or webkit had problems with this site.

#4

What about Youtube videos, still that reduced, pink coloured image?You could also provide more info on gpu and driver etc.

#5

It happens with everything that uses Flash: YouTube videos, banner ads, MiniClip games, the whole nine yards. I just had that site up to try disabling hardware acceleration (without success–the settings dialog is also caught in the pink overlay/reduced thing and is unusable). I’ve only had this problem on this computer. I believe it is Flash as opposed to something else because the Pepper-based Flash in Chrome works fine (I just don’t really want to use Chrome).

The ThinkPad has an Intel 82852/855GM Integrated Graphics and is running with the i915 kernel module driver. KInfoCenter says the renderer is “Mesa DRI Intel(R) 852GM/855GM x86/MMX/SSE2.”

This seemed somewhat similar: http://askubuntu.com/questions/420977/graphics-problem-with-lubuntu-13-10-on-amilo-pro-v2020

If you haven’t done so yet, you could first try to deinstall Flash, remove the .adobe and .macromedia folders from your home directory, reinstall Flash, start Konqueror and scan for new plugins.
Also, make sure that neither Gnash nor Lightspark (or similar alternatives) are installed.

It seems like a graphic driver issue, though, but the steps above shouldn’t do any harm either way.

A bit old but this seemed to provide a solution which might be relevant: http://ubuntuforums.org/showthread.php?t=1687772

IIRC
You need to disable hardware acceleration

F_Sauce, I’m going to give the Intel graphics drivers a go (from your http://askubuntu.com/questions/420977/graphics-problem-with-lubuntu-13-10-on-amilo-pro-v2020 link). I’ll let you know how it turns out.

Caf, I was trying to disable HW accel, because I did find several sites that suggested that, but it’s impossible to disable because of the squished/pinkified state. Do you perhaps know of an alternative way to disable HW accel?

Thank you guys so much for your help, by the way! I apologize for not getting back sooner – break just started, so I’m trying to get adjusted to a different kind of hectic!

#10

I think if you install: flash-player-kde4

Which is a settings manager for flash in kde
It should have such a setting
Once you install it, you should find it in the menu by search for: flash

Hi Carl.

Isn’t the hardware acceleration issue related to NVIDIA only, I think so?

Greetings
Could be. I can’t recall for sure.

Hi F & Caf (and others who may have the same issue),

I’ve had a chance to investigate a few different things, and this is what I’ve found:
(1) I ended up not compiling the intel drivers from source, would have required downloading a whole bunch of things and compiling, including a new kernel, it seems from Intel’s documentation. They only provide compiled drivers for Ubuntu and Fedora.
(2) This is definitely a graphics driver problem. For whatever reason, hardware acceleration isn’t working for the Intel 855 with the drivers provided. Running glxinfo shows the following error “Error: couldn’t find RGB GLX visual or fbconfig” twice. Thus, despite what KInfoCenter seems to indicate, hardware rendering is not working properly. This is verified by adding i915.modeset=0 to the boot loader options, which uses FBDev as a renderer, rather than the included Intel drivers. YouTube works fine when using FBdev. Also, Opera looked really weird when using just the Intel driver; using i915.modeset=0 resolves the graphical issues, further confirming the problem lies with the graphics drivers. This probably explains why disabling hardware acceleration in Flash would likely resolve the graphical issues on YouTube etc.
(3) For Caf, the flash-player-kde4 package does bring up a settings window, but it doesn’t provide an option to change hardware acceleration, unfortunately. (Seems kind of a questionable design decision by Adobe, because you can change all of the other settings but the hardware acceleration)
(4) The 13.1 release notes, in section 5.1, indicate that some changes were made relating to KMS drivers for Intel, ATI, and Nvidia. It mentions that legacy Intel GPUs can use the ‘intellegacy’ driver, provided by xorg-x11-driver-video-intel-legacy, to use UMS rather than KMS. However, this package is not in the 13.1 repositories, under the name in the release notes or any other name (that I could find).

However, I’ve download the RPM from http://software.opensuse.org/package/xorg-x11-driver-video-intel-legacy for openSUSE 12.2 (the Factory version doesn’t seem to be working). I will try and see if I can get that to work and let everyone know.

#14

Could you please post the file /var/log/Xorg.0.log? That should provide a clue whether there’s a problem with the intel driver.

One thing you should try in any case is switching to the older (but stable) UXA acceleration.
See here for a howto:
https://en.opensuse.org/SDB:Switch_xf86-video-intel_to_UXA

(3) For Caf, the flash-player-kde4 package does bring up a settings window, but it doesn’t provide an option to change hardware acceleration, unfortunately. (Seems kind of a questionable design decision by Adobe, because you can change all of the other settings but the hardware acceleration)

You can right-click on a flash-video and choose “Settings” to get to the hardware acceleration setting.

(4) The 13.1 release notes, in section 5.1, indicate that some changes were made relating to KMS drivers for Intel, ATI, and Nvidia. It mentions that legacy Intel GPUs can use the ‘intellegacy’ driver, provided by xorg-x11-driver-video-intel-legacy, to use UMS rather than KMS. However, this package is not in the 13.1 repositories, under the name in the release notes or any other name (that I could find).

That’s old news. (11.1?)
And the intellegacy driver doesn’t exist anymore.

However, I’ve download the RPM from http://software.opensuse.org/package/xorg-x11-driver-video-intel-legacy for openSUSE 12.2 (the Factory version doesn’t seem to be working). I will try and see if I can get that to work and let everyone know.

Don’t! It won’t work.

#15

Wolf, you’re a genius! Switching to UXA has resolved the issue. Thank you!

In regards to the other things,

(1) If you or anyone else is still interested, I’ve copied and pasted the Xorg.0.log (from before the UXA change) below [excluding non-graphics sections].
(2) Yes, I know the Hardware Accel for Flash is available by right-clicking and going to settings, but it wasn’t usable, as it was squished and everything, and trying to click on it to disable HW accel just froze Flash.
(3) Wish I’d read your comment before trying, because it definitely doesn’t work.

Thank you all for all of your help!

Well, there’s nothing unusual in there.
But the intel driver version shipped with openSUSE obviously has a bug in the SNA acceleration code for your particular chip.

If you wanted to, you could try the latest intel driver from the [noparse]X11:XOrg[/noparse] repo. In that case, you would have to switch the whole X/Mesa stack to the versions from that repo as well, though.

You could do it like this:

sudo zypper ar http://download.opensuse.org/X11:/XOrg/openSUSE_13.1 X11:XOrg
sudo zypper dup --from X11:XOrg

No idea whether your particular bug would have been fixed already, though.
And you might also have to update to the latest kernel from http://download.opensuse.org/Kernel:/stable/standard/ to be fully up-to-date (part of the intel driver is in the kernel).

Or just stick with UXA acceleration for now. I don’t think you will miss much…

I was having the same issue some time ago with my installation from full dvd kde 13.1 32 on a machine with i855

I found a post here with this:

Create a file /etc/X11/xorg.conf.d/20-intel.conf

and put the following text into it:

that solved the flash and the opengl problem in desktop effects :slight_smile:

Well, that’s exactly the same the OP did now, and it solved his problem as well.
Have a look at his previous post.

What your 20-intel.conf file does is switch from the new SNA acceleration to the older (but stable) UXA acceleration.

yes I seen the post but I’m thinking if it is the same putting the file in different placement or one is better then other?

technically speaking… :slight_smile:

It depends.
The filename does not matter at all, but X reads those files in alphabetical order. That’s the reason why they all start with a number (to make the order more obvious).

On a default openSUSE installation there’s only 50-device.conf with a Device section, which has all lines commented out (just as 50-monitor.conf and 50-screen.conf).
So it makes absolutely no difference whether you create 20-intel.conf, 50-mydevice.conf, 80-xyz.conf, or append those lines to 50-device.conf.

The name might make a difference though if you also have other files in /etc/X11/xorg.conf.d/ which contain actual configuration snippets.
