Screen blinking/flickering

Hi, whenever my screen goes to sleep and I resume (lock screen) my screen starts blinking every 3-5 seconds. It goes completely black (probably turns off) for in the order of microseconds. Happens with Fedora, Ubuntu, Arch & Manjaro. Have not tried other distros. GPU is Amd picasso/Nvidia 1650. Using AMD for X11, but is present if I use nvidia too by prime-select scripts. Desktop environments Gnome X11/Wayland and KDE X11. Please help.

Apart from DE's, the issue is present in VT's too.

If it appears on any distribution - logically - it is hardware related.

We can't help with that.
