I have got a really weird problem. When I scroll a web page, look through images really fast with right arrow held or render something with OpenGL on high fps, I have got this flickering horizontal line at the center of the screen or a little bit lower. It feels like the system cannot handle redrawing of large amounts of changing pixels, change buffers quickly or something along those lines.
I have just installed Ubuntu 18.04 MATE, 410 NVIDIA driver and apart from that the system is clean. I can't figure out how to fix this and why this is happening. Oh, and one last thing - I have got GeForce GTX Titan Black, maybe this has something to do with the problem.
