--- Comment #4 from Grzegorz Kowal custos.mentis@gmail.com --- Yes, I already did it.
The problems appears after commit
f15a7f3c6e1bb802ae8c2a29a2dc35ff530aea4d - mesa: Use the effective internal format instead for validation
which is related to GLES3. I should note that I was using kwin_gles. With standard kwin, the problem does not appear with Mesa 11.0.1.
