dmesg

Hello, I would like to report a list of issues I've run into after some time of
using mesa gallium driver for AMD Radeon 7790 (BONAIRE Sea Islands chip).

Used components:

OS: Gentoo
User space packages:
media-libs/mesa git
sys-devel/llvm git
x11-libs/libdrm git
x11-libs/glamor git
x11-drivers/xf86-video-ati git
x11-base/xorg-server 1.14.3

Linux Kernel: 3.12.0-rc7

Rendering issues (tested with window managers: metacity and compiz):
- rendering corruption while scrolling web pages even if inbrowser hardware
acceleration is disabled (in Chrome as well as in Firefox). There is kind of
pixel offset on the diagonal of rendered web page and corruption of images,
borders (it happens only while scrolling).
- Taking screenshot and using gksu (I'm using gnome 2 environment) results in
huge rendering slow down (about 1 fps). I have to reload a window manager to
fix this issue.
- Introduced dpm to Sea Islands in 3.12 kernel (while enabled) leads to image
corruption when moving windows, playing videos (in a browser and a video
player), scrolling websites. The corrupted image shows as flickering and
messing around parts of the screen. The rendered image is ok only if nothing
happens on the screen.
- anisotropic filtering doesn't seem to work (tested in sauerbraten game).
After applaying there is no visual difference between bilinear filtering and
anisotropic filtering.

Stability issues:
- Any use of OpenGL hardware acceleration after few minutes leads to GPU lockup
(from basic OpenGL games like sauerbraten, inbrowser hardware acceleration, to
compiz window manager). Glamor + metacity seems to work without GPU lockups.
- Playing videos in mplayer (VO: [vdpau]) also leads to a GPU lockup from time
to time. The same happens in firefox browser while playing youtube videos in
uvd decoding + flash 

Performance issues:
- I get much less fps compared to my old card - Radeon 4850 (r600g driver) even
if the clocks are manually set to a maximal frequency.
- Compiz with basic effects is sometimes not fluent - drops to less than 30 fps
especially when there are more windows opened.

I would like attach any GPU lockup logs but dmesg doesn't leave any trace. More
than half of lockups are not recoverable and I have to reboot the computer.

Screens and logs are in the attachments.

Thank you for any help in resolving these issues.
