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. How reproducible: every time Steps to Reproduce: 1. Choose resolution above 1024x768 2. Enable Desktop effects Actual results: right hand side of screen garbage Expected results: nice desktop effects. Additional info:
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 isn't working. 'Desktop Effects' cannot be enabled. I am using a wallpaper (*.jpg) on my desktop. I have an ATI rage 128 SM/4x AGP/4x Expert 2000.

(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 2.8.1.1 doesn't save its sizing - can't start as panel icons - insist on starting maximum - notecase [filename] - stickynotes_applet - xchat-gnome - 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. Section "Monitor" Identifier "Monitor0" 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 Option "dpms" EndSection Section "DRI" Group 0 Mode 0666 EndSection 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 is unchanged. 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 7000/VE] (1002:5159) as well as 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY (1002:4c59) 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.
