Question problem: Screen recording software records only top,left quarter of the screen

I'm trying to record my screen on Ubuntu Mate 18.4 with Nvidia P2000 and Nvidia proprietary driver.
The problem is that all software I tried (Kazam,SimpleScreenRecorder,OBS) record only top,left quarter.
Video resolution is 1920x1080 when I use 4k and drops to 960x520 when I switch to FullHD. Looks that software thinks the resolution is lower than actual value. When I switch to "select area: mode and drag selection rectangle to cover full screen it shows 1920x1080 dimensions for 4k and 960x520 for FullHD.
It doesn't matter whether I have dual-monitor configuration or not.

On the other hand: when I take a screenshot - everything is perfectly OK.

What can I do with such issue?

Have you tried using ffmpeg? It's x11grab is probably a little more low-level than the other tools.


screen resolution, screengrab
