To be honest I think this is just something wrong with X server/mesa /glvnd
layer.

I do not see this on my compilation of cingg when running with mesa
git/xserver git.

Because I think we both on amdgpu/radeonsi now common parts should be ok....

May be get apitrace installed and ....  file another bug at Mesa3d
bugtracker?
