Yes your kernel log is showing lots of errors:
[ 808.338925] [drm:drm_mode_addfb2 [drm]] [FB:75]

However we are unable to help in this case because you are using an
unsupported PPA ("oibaf") for your graphics libraries, which is not from
Ubuntu. We often find that's the cause of serious graphics bugs. So this
bug will be marked as invalid. Please uninstall that PPA and then if you
continue to have problems feel free to open a new bug.
