Ah, this is on Radeon HD4350, Mesa 7.10.2 R600c, kernel 2.6.38.4, KMS. Can you try r600g? It was quite good in 7.11 with R600g. But it is back with even worse effects on a nightly version before 8. Can you bisect r600g? Still an issue with released mesa 8.0 or with mesa git ? Yes, happens with 8.0-rc2 (kernel 3.2.5, ati 6.14.3, libdrm 2.4.30). Even got this: radeon: The kernel rejected CS, see dmesg for more information. [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12! Will try git later after some weeks. But it was fine in 7.11 but I can't do bisecting right now. Mesa 8.0 is pretty outdated, could you please retest with a more recent version of mesa? No, I have not seen this specific problem for a long time now. Thanks. |

Created attachment 46261 [details] See the blue dotted band around the planet - it is a window titlebar. Textures on the planet Earth are rendered garbled with data pixel taken from other windows (programs), probably taken from released GPU memory. Note it only happens on Earth. The garbled texture is not the planet surface one, but it is the clouds layer. That is loaded from a file that is 1024x512. It does not happen when lowres textures are selected. Then a 128x64px file is used for the clouds.
