apport information ** Tags added: apport-collected
** Description changed: Sometimes the following graphics glitch is triggered where the screen starts moving/rotating rapidly. See https://i.imgur.com/u6j5auo.gif (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. And I apologize if this isn't the correct place to report. I've already tried a couple of places with no replies or help whatsoever.
