Bug Description
This is likely a wayland issue. I can't bear the tearing if I don't use wayland.
I get screen flickering (approximately every 5 seconds) and some windows seem to bring up some mis-colored moving artifacts that clear when the window is closed.

I believe I have corrected this by changing my refresh rate from 59.99 Hz to 59.86 Hz.
Is this a requirement for 2560x1600 resolution on DL-DVI? Should this perhaps be communicated upstream to someone who knows better?
