After resuming the the screen is smaller

[llo94]

Expected behaviour

When the screensaver is activated and when I unlockscreen, I expect the screen to stay with the same size as before the screensaver activation

Actual behaviour

I use a 4K desktop on a 4k display. When I leave my desk, the screensaver is activated after 10mn. When I come back, the screen is not fully usable. The bottom and the right edge of the screen are not accessible with the mouse. There is an invisible wall which block the mouse.
If I change display resolution, then the non-accessible parts of the screen could be scrambled and not well refreshed.
The accessible part of the screen still ok.

Regain a correct behavior is possible by executing a randr command, for instance this one works :
xrandr --output HDMI-A-0 --scale 1.0x1.0

Steps to reproduce the behaviour

Leave the workstation until the screensaver is activated then unlock

To my knowledge, mate-screensaver does not change screen resolution and scaling ratio
