Calling glClientWaitSync under specific conditions will run in=
to an
unrecoverable deadlock.

The only known workaround is to issue a glFlush before glClientWaitSync.

I originally discovered this problem in the Dolphin Emulator, see ticket
https://bugs.dolphin-=
emu.org/issues/10904
However I am now reporting it because I was able to reproduce this bug
independently.

Reported affected systems so far:
Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz
16GB RAM (1 stick)
GPU: Radeon RX 560 Series (POLARIS11 / DRM 3.19.0 / 4.14.11, LLVM 6.0.0)

I will try to upload a simple repro if I can in the next few hours.
I stumble on this issue because our Ogre 2.2 sample "Sample_PlanarRefl=
ections"
is affected by it.

My git version is stuck at 847d0a393d7f0f967f39302900d5330f32b804c8 due to =
an
unrelated regression reported at
https://bugs.freedesktop.org/show_bug.=
cgi?id=3D105218

However I know the bug is still present as of
1f5618e81c00199d3349b1ade797382635b2af85 (which is not latest)
