The glitch with gedit

Sometimes the following graphics glitch is triggered where the screen starts
moving/rotating rapidly. See attachment or <a href="https://i.imgur.com/u6j5auo.gif">https://i.imgur.com/u6j5auo.gif</a>
(gedit on LXDE).
This is triggered semi-randomly while using specific apps like Kate, gEdit,
gVim, leafpad, embedded console inside Dolphin, KDevelop and rarely with
Konsole.
Also triggered for a few split-seconds when I move the mouse when in fullscreen
mode in VLC but stabilises quickly. However, everything is stable when I just
use Chrome or Firefox, LXTerminal, Clementine and Code::Blocks, even for hours.

Whenever this is triggered, it can sometimes be fixed when I switch to desktop
or Chrome or a different app while closing the trigger-er app while other
times, rebooting is the only way. Sometimes (rarely) the screen becomes
completely black after a while, with key-presses and mouse movements revealing
the screen for split-seconds which allows me to properly shutdown/restart the
laptop.
I've tried to Google the problem with no results, I'm not even sure what to
search for.
