corrupted pixmaps

Does mesa from git work any better? I've done more tests (with gnome-shell 2.29.1 + clutter 1.2.8): -with Mesa 7.8.2 and KMS disabled, I don't see any pixmap corruption (but gnome-shell become very slow) -with Mesa git and KMS disabled, windows are not visible at all (only the shadow is visible) and gnome-shell is also very slow. I'll do more tests tomorrow, when gnome-shell git is buildable again, since I think the slowness was fixed in git. Ideally you'd use mesa git and kms as that enables additional hw-accelerated GL functionality (readpixels, etc.) that should improve gnome-shell performance. hmm, trying mesa git with kms is even worse ATM : gnome-shell (2.29.1) doesn't respond to anything and does refresh correctly ; kernel states : drmRadeonCmdBuffer: -12. Kernel failed to parse or rejected command stream. See dmesg for more info. Can you attach your dmesg when that happens? Created attachment 37925 [details]

We might overflow command buffer. *************************************************************************** Bumping VRAM to 64MB fixed r200_swtcl.c warnings. I've upgraded Mesa to 7.9RC2 and this corruption is fixed (there is other issues but there is a also a lot of Cogl errors, so it might be Clutter master bugs). Closing |
