Public bug reported:
If darkttable is running fullscreen (F11) on Ubuntu 18.04 with my
Thinpad T480s, there are annoying flashes of the screen in fullscreen
mode on iteraction.
For example: If I adjust the base color curve while on fullscreen, the
start and end of the mouse dragging the curves control points often
result in brief (almost a single frame) white screen flash.
This is extremely disturbing when working in dim environments suitable
for image processing.
The bug does not seem to occur if darktable is run in windowed mode.
