Ever since I started using openSUSE at the end of December, this has been bugging me. When I try to watch a full-screen YouTube video in either Chromium or Firefox, it lags to the point where maybe I’m getting 0.5 frames per second. Ironically, when I launch Chrome in virtualized Windows 7 (VirtualBox) to watch a full-screen Flash video it looks smooth as butter. Yes, even with the virtualization overhead and everything.
I’m using Adobe Flash 10,3,181,22 from the openSUSE repositories, Chromium 15 and Firefox 5. I’m on a 64-bit system. Any ideas as to what could be causing this lag?

You did not indicate your video setup, but that is important. In the message above, he was using nVIDIA. Ignore that part if you have AMD or Intel video. There is a different AMD solution and most often, a newer kernel version can help with Intel. Dual graphic chipset Laptops can be problematic though.
I use the fglrx driver for my ATI video card. I don’t think the issue is related to my video card, because Flash works fine when I run it inside VirtualBox. Why doesn’t it work out of the box?

I do not know if there is a simple explanation except to say that the emulated video hardware world presented by VirtualBox has been tested and modified to work properly with Flash. In the real world, Flash must interact with real video hardware and drivers. I would suggest you give the new 64 bit Flash a try and see if it helps. You do not need to change the Flash version in the emulated world since it works OK.
I got the same problem with Flash, under an Nvidia card. The problem is Flash it self, since it has a wrapper “around it” that makes it works under a 64 bit system. To see if things are better you could try flash player 11 beta Adobe Flash Player 11 Beta for Desktops | applications, content and videos - Adobe Labs that has native support for linux under 64 bit. Maybe this will improve the quality of youtube video in fullscreen
I reported the same issue couple weeks ago in another thread. In my case, the fglrx driver is the culprit … as far as I can tell, because I don’t have the problem on nvidia systems with exactly the same programs installed. It started at some point under 11.3 - it worked before - I don’t remember after which update. I tried to downgrade the driver to several previous versions (atiupgrade can be used to downgrade Catalyst as well) but it didn’t help. Then I installed 11.4 on this machine (iMac with Radeon HD 2400 XT) but no change. Since then I keep upgrading both Flash Player and the ATI driver, but Flash videos never worked in full screen again: as soon as I switch in full screen Xorg is eating 100% of the CPU resources, the video becomes extremely slow or freezes and I can hardly move the mouse to exit fullscreen, so that when I might end up killing firefox. Same problem with other browsers (opera, chromium) and with the 64bit plugin (whether I deinstall the wrapper or not). So I haven’t found the solution nor the explanation.
I currently have the 64-bit opeSUSE 11.4 installed on this laptop and have similar issues. I’m about to make the switch and install openSUSE on my desktop … when I do that, I’ll install the 32-bit version. I’ll let you guys know if I experience similar issues there. Should be a week or so.

I do not know what video you are using on the desktop, but with nVIDIA or Intel, I would not go with 32 bit openSUSE. I can’t say about AMD/ATI, but I guess I would state the desktop video system you have and why you hope 32 bit will be better for you.
Oh… it seems i forgot the mention my OS: Tumbleweed @ 64 bits with KDE 4.6
Here is a repo with a precompiled package of Flash 11 beta: Index of /repositories/home:/Grieff
Under KDE, in Desktop Settings -> Desktop Effects -> Advanced, uncheck “Suspend desktop effects for fullscreen Windows” *.
It actually works even better under KDE than under all other desktops - amazingly! Without compositing, Xorg eats 100% of the CPU resources. With compositing, it takes about 50% (on Gnome, Xfce, or any other using xcompmgr), while under KDE it used 26% (!) for me.
I’m going to add this setting in my compositor script.
What the… turning on desktop effects while on full screen makes the problem go away magically like you said! It’s exactly the opposite of what I would expect (which is why I read it wrong the first time), but it works! Thanks man!
