Priority: medium Bug ID: 81546 Assignee: dri-devel@lists.freedesktop.org Summary: Radeon 7990: Output of most applications garbled, Gnome shell mosly fine Severity: normal Classification: Unclassified OS: Linux (All) Reporter: mail@marcelschaal.de Hardware: x86-64 (AMD64) Status: NEW Version: unspecified Component: Drivers/Gallium/radeonsi Product: Mesa

Created attachment 103116 --> https://bugs.freedesktop.org/attachment.cgi?id=103116&action=edit Screenshot of Gnome shell

Please have a look at the screenshots. Rendering of most windows is totally garbled including window decoration. This is not about Crossfire/SLI/Multi GPU rendering, just plain single GPU.

Gnome-shell's own rendering is mostly fine. Panel, lock screen animations, menus and dashboard don't show distortions. KDE's/Kwin is worse, even the panel's are broken, but it's able to draw window decorations. glxgears's rendering is fine. Linux console (no X11) is also fine.

Hardware: PowerColor AX7990 6GBD5-2DHJ, which is one of those fake 7990s that actually use 2x7970 Tahiti XT on a single PCB and not 2x Malta. Other GPUs (6950/7950) were working fine with that system.

Software: Fedora 19/20 (From stock LiveCD image to current updates incl. Kernel 3.15.4) There were no (drawing!) issues when I was using catalyst.
