** Description changed: The bug I see on my Dell D830 (8GB RAM, Nvidia G86M [Quadro NVS 140M] (rev a1)) with nouveau driver using Kubuntu 16.04. After login everything seems to work fine for roughly 2 minutes. After that flickering and tearing starts (when moving windows around with the mouse) and gets more intense until the screen is full of "color-blobs" (which means: one cannot see anything anymore). Starting a flash movie in Firefox provokes immediate tearing and flickering. Restarting the kwin compositor helps - for another 2 minutes, then the whole problem starts to catch on momentum again. I tried everything mentioned here: http://askubuntu.com/questions/672007/flickering-in-kde-plasma-5-4 the only thing that helps for a longer period of time is turning off compositing completely. I am unsure where to further look for the problem: Is it kwin? xorg? nouveau? All of them? Whatever? The logs I checked (xorg, syslog, dmesg etc.) contain nothing that I can make sense of. I'd appreciate any hint to where (and: what) to look (for) and which more specific information to collect ...
