Cannot confirm (linux 970m), might be tied to Intel 620...

@Nico Tex (nico14916) : are drivers up to date?

@Clément Foucault (fclem): does this ring a bell?

I have the latest recommended driver from Dell.

I remember having fixed this problem... I think it was rB117bc96ce88474d3c6b28e669e6ee339441051fb but if this is back, that means your GPU passes through the
detection somehow.

I've added a new "--debug-gpu-force-workarounds" to test gpu workarounds bypassing the detection. It should be in the next build (in 45minutes from the time of this comment).

If running from command line with the --debug-gpu-force-workarounds option does not work then it's a bit hard to guess what's wrong. Maybe a glFlush() or glFinish() missing somewhere.

It work perfectly. No more issue on viewport and on render with "--debug-gpu-force-workarounds".

Could you please paste your system-info.txt so I can list your gpu for the workaround.
