I am also experiencing this kind of issue. For me, the problems manifest as buggy display of video when VLC is in windowed mode. (Fullscreen mode is fine.) Also, when I suspend my laptop, the display is partially corrupted when I resume. See here: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1452318
The UXA tweak does work for me, but makes my laptop noticeably slower, and unusable when I run Virtualbox (this is something I have to do quite a lot, so it a bit of a deal-breaker). I am also using a new Dell XPS 13 and see similar log messages to Moritz Heiber in post #106 above. Is it safe to try the test packages from post #100 in vivid?
