Emacs giving me artifacts in GUI

xolve · May 12, 2011, 6:50am

I am using emacs for editing. The problem is that it is giving me a lot of artifacts on the screen. Like the cursor movement leave black marks all over the screen. Cursor is sometimes not visible after movement. If I use highlighting current line then it also leaves artifacts.

Please help.

Ok, I found that KWin effects are the problem here. If I can somehow disable KWin only for Emacs the artifacts would be gone. Anyone can help me now please.

Sometimes, killing plasma-desktop and kwin, and restarting them works !

Don’t know how to nail this one, are there any reported bugs, which might have been fixed in KDE 4.6.3 or later?

Sounds more like a graphic driver problem (who knows). Can you post your oS
version, architecture and graphics card model and driver in use now?
(Read the stickies in the multimedia forum what info is usefull to help).

My OS is openSuse 11.4. My graphics card is:

Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

And the kernel is:

Linux ravi.iitg 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 i686 i686 i386 GNU/Linux

The emacs version I am using is: 23.2.1

The Kwin effects are working fine and as such I am not facing any graphics problems in other applications or video playback.

I see you never ran the updates on your system, is there a special reason
not to do it? I am not too familiar with the intel graphics, but there was a
regular update for x11 some time ago which was almost solely for fixing bugs
with intel graphics cards.
So if you have no special reason to avoid the regular updates for your
system I would do it now (it makes also sense to have a secure system).
From a terminal you would do it like this


su -
zypper up

But maybe someone else has an additional comment on this and you want to
wait.

Thanks that really worked and I am not facing any problems with Emacs. No I will be taking applying updates more seriously.
