4.8-dev ~ GTK File Dialog Lags and Freezes
Today I built UE4's editor from source so that I could give it another try. One problem I noticed (which I find to be very unusual) is that the GTK file selection dialog is showing performance problems. It is slow to repaint and whenever I use it a second time in a session, it freezes after selecting a file. The file is selected and I can continue working, but the file selector remains behind as a "zombie" window that won't go away even after the UE4 editor is closed. When this happens, I need to force-kill it to make it go away.
Perhaps a bad version of GTK was packaged with the build dependencies?
Operating System: amd64 Manjaro Linux, kernel 3.19

The slowness should be fixed with this commit: https://github.com/EpicGames/UnrealEngine/commit/187fa3c94eccb664ca0d1e278e94fbae3ca35de5 . Not sure about the freeze, this may need further investigation. We're however in process of developing our own (even if less featureful) open/save/etc dialogs which hopefully will solve those problems once and for all :)
