Xorg log
As you can see in the kwin stdout output, radeonsi only supports OpenGL 2.1 in Mesa 9.2. I suspect the problem happens when kwin tries to create an OpenGL 3.x context, but I wonder if this is radeonsi specific — does it not happen e.g. if you run kwin with LIBGL_ALWAYS_SOFTWARE=1 ? I am not sure how to confirm it. I tried launching: LIBGL_ALWAYS_SOFTWARE=1 kwin --replace > kwin_stdout_LIBGL_ALWAYS_SOFTWARE.txt 2> kwin_stderr_LIBGL_ALWAYS_SOFTWARE.txt and it disabled desktop effects; then I tried to switch to OpenGL 3.1 + Raster and Kwin crashed displaying 'report bug assignment' window and then was restarted automatically without effects. I could not enable effect anyhow. kwin_stdout_LIBGL_ALWAYS_SOFTWARE.txt was empty. Created attachment 86794 [details]
kwin stderr with LIBGL_ALWAYS_SOFTWARE=1
Pretty much old bug, is this still an issue with current mesa? |
