[radeon driver] Screen corruption when "Applications" has enough apps to have a scrollbar
Last modified: 2012-01-06 12:16:14 UTC
Whenever I have enough applications installed on computer to force gnome-shell's display of applications to have a scrollbar I get a ... display issue? I'm not sure exactly what's its called but I know it's not supposed to be there. I have attached a picture to demonstrate.

This is almost guaranteed to be a driver issue.
Is there anyway to confirm whether or not it is? A test of some sort? I'm willing to try it.
Hard to tell. The only test would be to change your graphics card/driver on the same computer. But a good indication that it's a driver bug is that most people don't see these artifacts. Could you give us the name of your graphics card and driver version? You should probably report this upstream if that's a free driver.
The video card is on-board. Video Card: VGA compatible controller: ATI Technologies Inc RS880 [Radeon HD 4200] Drivers: VESA: driver for VESA chipsets: vesa FBDEV: driver for framebuffer: fbdev
Are you really using the vesa driver? Then, that would be a bug in the software renderer... Could you attach the output of glxinfo and /var/log/Xorg.0.log? What's your distribution? Isn't there a better suited driver for your card (like the new "radeon" free driver)? (Note I had a bug recently with modesetting not being enabled on boot on an AMD card, and the vesa driver was used as a fallback. That's a second issue.)

I'm using Fedora 16
Thanks. So you're using the free radeon driver, which is probably the best for your card. As it's still a little young, visual artifacts are not completely unexpected. ;-) Could you report this upstream? The bug tracker is https://bugs.freedesktop.org/enter_bug.cgi?product=xorg (product Drivers/Radeon) Please provide them with all the information you gave here. I'm closing this report as there's nothing we can do from the GNOME side. Feel free to update it with new information (like the link to the driver bug report).
Reported, as you requested. You can find it here: https://bugs.freedesktop.org/show_bug.cgi?id=44524 Thanks for the help!!
