    Exclamation Strange graphics problem on Lenovo G50-80

    Sometimes the following graphics glitch is triggered where the screen starts moving/rotating rapidly: 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 mostly be fixed when I switch to desktop or Chrome or a different app while closing the trigger-er app. 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.

    Some more details:
    OS: Lubuntu 16.04 (Kernel 4.4.0-22-generic)
    Current DE: KDE 5.5.5 installed with kubuntu-desktop package (with no install recommends to save bandwidth). This problem also occurred with LXDE (thus openbox), so nothing to do with the DE.
    Laptop: Lenovo G50-80 with integrated graphics chip (Broadwell-U Integrated Graphics)

    Please tell me what more information I can provide.

    I don't have Windows either to test the graphics stability there.
    This is extremely inconvenient deterring me from using specific apps, I'd really like this solved.

    Bump. (Sorry, it's been 10 hours, had to do this)

    Update: I did an apt upgrade which included kernel updates, graphics seem more stable, however when the glitch is triggered is becomes impossible to clear it without a reboot

    Installing 'xserver-xorg-video-intel' fixes the problem.
