--- Comment #29 from Michel Dänzer michel@daenzer.net --- (In reply to Yves W. from comment #27)
- with default driver and default kernel (Linux Mint 18 -> 4.4.0-38-generi)
it's working at 2560x1440 @144hz, no flickering issues.
-> tried using the Ubuntu 4.8.0 kernel -> flickering at 2560x1440 @144hz,120 and 100hz. only 60hz works without flickering
Can you bisect, or at least narrow down which version between 4.4.0 and 4.8.0 introduced the problem?
