Felix has already mentioned that there is a fix in the works (which is a simple value tweak in a shader), posting more screenshots at this point won't make much of a difference.
Seems to be hardware specific (your iGPU), your drivers are updated...
Will probably be fixed in the future and likely to be cause of the OGL 3.2 update.
Does it make sense for the debug screen to show OGL 3.2 now instead of OGL 4.6 like before?
OGL 3.1 at max.
