Issues with tooltips in UE4 Editor [Ubuntu 16.04]
Quickly moving the mouse over anything that has a tooltip causes the FPS to drop significantly. Furthermore, doing it in menus makes the entire UI freeze for a short period of time. Watch the video for a demonstration: https://youtu.be/cZqBSivYtAc
Specs: Ubuntu 16.04, 8GB RAM, i3 3.07GHz, Geforce GTX 750
I know it is not a real solution for you guys but I really can't recommend using Unity as DE for UE4. It makes the UE4Editor super slow and laggy. Personally I am using XFCE and have no problems with the issues from above. When I use UE4Editor on the Unity DE it gets quite slow. It is a known issue that the smear effect appears when you don't have a compositor but you can switch your compositor off to make things faster but be aware that it might cause "smear" effects like issue as @brothermechanic mentioned.
