I believe I'm having this exact same bug on a similar machine. LT3108h. I'm not too well adjusted to linux but if you'd like me to run any reports to see if I can help let me know. Screenshot matches similar issues I am getting, the corruption seems more random on my side and gets heavier the longer I leave it alone.
