Fullscreen mode glitches

When in Fullscreen mode with Fullscreen viewer on!
When changing pages, screen flickers a bit.
Most of the time drop downs are invisible but clickable.
Neither happens when not in Fullscreen mode and/or Fullscreen viewer.

For anybody to be able to help you need to tell us your system specs. OS, ram, GPU, version of Resolve, etc.

SSD's all over the place
