Fullscreen loop flickering and touchpad not working

Hello all,

For some reason, all windows (terminal, web browser, …) started to get full screen automatically, but deactivate full screen at same time, like flickering. There is no regular interval, it just happen between few minutes interval.


Also, the touch pad stopped to work, and I can’t identify when running libinput list-devices. Actually I can see my wireless keyboard, but the touchpad is not listed there.

Finally, another weird thing is I press LSHIFT + P on my laptop keyboard “nothing happens”, I mean I can’t write P. When I press p alone it works, and also LSHIFT works with others keys. I checked on keyboard layout to show pressed keys and LSHIFT + P doesn’t show anything. However, when using xorg-xev, LSHIFT + P is listed as pressed.

Here is my system configuration:
