        <pre>The Black Mesa game has been released for Linux.[1]
Unfortunately, the game flickers every 2-3 seconds when I run it on my discrete
AMD card.

System:
HP Pavilion Laptop
Intel Sandybridge
AMD HD6770M discrete graphics card
8GB RAM
Kubuntu 16.10 with Kernel 4.8 (default)
Mesa 13.1.0-devel (according to kinfocenter) from the oibaf PPA
KDE Plasma 5.7.5

The screen flickering does not happen if I run the game on the integrated Intel
graphics card.

I tried the following without effect:
*) Changing graphics settings
*) Enabling/disabling desktop effects
*) Changing from two monitors to only one monitor

The bug is also reported to the Black Mesa developers in the steam forums [2].
If I can provide any additional information, please let me know.
