The default priority for the quality of service for the video output results in unsightly glitches on the output whenever there is memory pressure on the system, which happens a lot.
This sets the VOP QoS to high priority, which fixes this issue.
Can you point out how it reproduces?
Jagan.
To reproduce, run something like glmark2-es2-drm while also running stress --vm 4, you should see glitchy output on the HDMI on rk3328.
A more real-world test is to just run a desktop environment, you will see horizontal lines through the screen the moment you start typing in e.g. a terminal emulator.
