Bug ID: 98494 Summary: Screen flickering in Black Mesa game Product: Mesa Version: 13.0 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: wolfgang-wallner@gmx.at QA Contact: dri-devel@lists.freedesktop.org

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.
