It looks like a driver issue at the first impression but more information is needed. The problem persists in blender 2.78b. As a note: I am on Rawhide, so I had to downgrade libGLEW from 2.0.0 → 1.13.0 to make the f25 package you suggested work. (In reply to Kai A.

It would not matter. It appears the issue is related to Radeon GPU driver as I found a related problem on upstream bug report: https://developer.blender.org/T48817 I confirm the bug on my AMD/AMD hybrid laptop. However, I am unable to reproduce it on Virtualbox and Gnome Boxes. Need to further verify on nVidia and Intel hardware. Further research revealed a bug from upstream where blender with Window Draw Method set to automatic will not assign to Triple Buffer https://developer.blender.org/T49945 Could you try this workaround on terminal? LIBGL_DRI3_DISABLE=1 blender Setting LIBGL_DRI3_DISABLE=1 fixes the issue. Also changing blender to use Triple Buffering fixes the issue (File → User Preferences → Window Draw Method: Triple Buffer). Could you test this scratch build on rawhide? https://koji.fedoraproject.org/koji/taskinfo?taskID=18048028 It contains upstream patch that added missing AMD GPU detection. Please set Window Draw Method to Automatic and verify if the fix eliminates flickering on UI. Thanks. The build fixes the issue :) Excellent. The build is on the way.
