Red Hat Bugzilla – Bug 213435
Radeon (ATI) garbage with composite WM
Last modified: 2018-04-11 12:45:11 EDT
Description of problem:
If the composite window manager and Desktop Effects are enabled when resolution
is above 1024x768 then the right hand side of the screen becomes garbage (and
panels stop functioning as a result). Using
Radeon R250 [Mobility FireGL 9000] (rev 02)
Version-Release number of selected component (if applicable):
All packages up-to-date as of Nov 1.
Steps to Reproduce:
1. Choose resolution above 1024x768
2. Enable Desktop effects
right hand side of screen garbage
nice desktop effects.
Same problem (kinda). Re-installed from FC5 to FC6; display resolution changed
from 1280x1024 to 1600x1200.
My display has ground almost to a halt. Screen redrawing is painfully
slow. Various application gui are missplacing themselves on the screen
even after repositioning them after installing a higher resolution and
bunch of other small config things are going wrong. Saving sessions
'Desktop Effects' cannot be enabled.

FC6 installed the display at 1600x1200 resolution when it was previously
running 1280x1024 in FC5. (I prefer the 1600x1200 now that I've gotten
used to it.) I have a Compaq V90 monitor, installed as a generic CRT.
Some other problems that may be related
- TV reception using tvtime is unstable.
- slow redraw
- 'Chess' crashes; command line says GL: Warning: RenderTexture size is
restricted to size of framebuffer. If you are on Linux, consider using
GLX instead of SDL.
- 'Stellarium' produces unclear text
- Sessions problems
- evolution 184.108.40.206 doesn't save its sizing
- can't start as panel icons - insist on starting maximum
- notecase [filename]
- want to start background wallpaper first
- mail summary opens at random positions not top right as configured
I have added the following lines to xorg.conf. They are a direct lift
from the FC5 xorg.conf I used to use.
VendorName "Monitor Vendor"
ModelName "COMPAQ V90"
DisplaySize 350 270
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 30.0 - 94.0
VertRefresh 48.0 - 160.0
I seemed to be missing monitor, DRI and compiz components, but I am not
sure they are necessary.
If I enable desktop effects on my Mac mini (G4, Radeon 9200, FC6) the screen
becomes garbled. compiz works, but the display is distorted color-wise. It
also looks like the width of the display is being truncated to (my guess) 640px.
The GNOME panels and all windows shrink accordingly. The height of the display
After reading this bugzilla ticket I tried to reduce the resolution to below
1024x768 but the display remains garbled regardless of resolution. I also tried
16-bit instead of 24. No go. Just for kicks I tried EXA instead of XAA but
that doesn't work at all (X server dies instantly).
Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

Resloved the problems (somewhat) by buying a Radeon 9600 video card and a ATI TV
wonder 550. Each of them now have their own problems.
Aside from my G4 Mac mini mentioned above, this problem also occurs on:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon
as well as
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY
Both cases on i386 with all updates.
This appears to be the classic texture sizing bug. I'm working on code to size
the GART aperture more intelligently so we'll hit this less often.
Looks like a duplicate of bug 203282 where a workaround [namely adding a
suitable drirc file] is described.
