Description Lauri Kasanen 2011-10-21 01:58:03 UTC 
Originally filed as a mesa bug here:
https://bugs.freedesktop.org/show_bug.cgi?id=42050

Running -git ati (856583dbca9) and maximizing glxgears, the DDX gives too small a buffer to Mesa:

r300: I got a pre-allocated buffer to use it as a texture storage, but the buffer is too small. I'll use the buffer anyway, because I can't crash here, but it's dangerous. This can be a DDX bug. Got: 5083136B, Need: 5087232B, Info:
r300: texture_desc_init: Macro:  NO, Micro: YES, Pitch: 1472, Dim: 1438x863x1, LastLevel: 0, Size: 5087232, Format: x8z24_unorm

Does this patch fix the problem?

Sorry, I don't have the laptop anymore where this bug was found.

I haven't seen it on any other hw.
Comment 3 Marek Olšák 2013-01-10 12:06:58 UTC 
The error won't show up with Mesa master, because it mentions the x8z24_unorm format and depth buffers are not allocated by the DDX anymore. It's also weird that the DDX didn't enable macrotiling for the depth buffer, not that it matters now.
