Fullscreen mode editing glitches when activating OpenCL, Ubuntu 15.10
When activating OpenCL using the Nvidia Driver in fullscreen mode only, the screen randomly flashes when refreshing the screen. It happens when moving any slider to edit in Darkroom. Deactivating OpenCL or going out of fullscreen corrects the bug.

Correction and details: It does happen as well without OpenCl activated but strictly in fullscreen mode. As if the content of another window is appearing very rapidly. Just a pop once in a while, when moving a slider window, or selecting a develop module in another tab. My config is vanilla ubuntu gnome 15.10 with the nvidia display driver. If worth mentionning, I did install fedora 23 with the nvidia driver and was having the same issue. Thanks.

Fedora 23 x86_64, Gnome 3 with Gnome shell, nvidia driver, darktable 2.0.4.
I confirm the bug. OpenCL does not matter, darktable glitches in fullscreen mode with and without --disable-opencl option.
I have glitch when any drop-down box disappears. For example: darktable view -> open and rotate -> guides -> select any guide type -> glitch!
However, the problem is not persistent. I tried to investigate conditions (if it depends on other windows, etc) and moved few windows to another workspace… and darktable stopped glitching. Moving that windows back to original workspace did not restore the problem. :-(
