--- Comment #4 from Austin English austinenglish@gmail.com --- Backtrace: =>0 0xb6bda21e in libdricore9.2.1.so.1 (+0xf721e) (0x7d857f78) 1 0xb6bdccfc in libdricore9.2.1.so.1 (+0xf9cfb) (0x00000002) 2 0xb6be0cf0 _mesa_CompressedTexSubImage2D+0x5f() in libdricore9.2.1.so.1 (0x0032f0c8)
the crash is in mesa itself, likely upstream. Debugging symbols for wine/mesa would be helpful.
