micronaut: I'm seeing a thin diagonal line from bottom left to top right made up of coloured triangles appearing on screen during the game. Is anybody else seeing this, or know of a fix?

Intel skylake core m3-7Y30
Ubuntu 16.04

Thanks for any help
Hello micronaut!

I've never heard about this issue, but you could try updating your video card drivers. You can do so by following these instructions (I'm assuming you use an integrated Intel video card, since that's the only piece of hardware you mentioned):

http://www.omgubuntu.co.uk/2017/03/easy-way-install-mesa-17-0-2-ubuntu-16-04-lts

Let me know if that helped! You can also contact our support here: https://support.gog.com/
