I have Radeon 5700 RX
I installed fresh version of Ubuntu 18.04.2 and installed drivers from the website. Otherwise resolution is very low.
With drivers all looks good - the resolution is correct and I can set the refresh rate.
The problem is that every approx 5 seconds mouse cursor freezes for about 1 second.
This happens only on the target resolution of my display (3440x1444). If I fallback to 2560x1080 then cursor seems fine. But this is below screens default resolution
I tried to install os and the drivers three times now, each time with the same effect.
Can I get some help with this please?
