Editor glitches when resizing window(5.3.5)

UI elements flickering and missing in 5.3.5. I tried to delete my project settings, delete the Library folder, delete the unity folders in %appdata%, refresh/reimport projects, but none of these solve the problem. Please watch the videos:

5.3.4

5.3.5

What should I do? Thanks!

No replies? The UI elements not only disappear after resize, they also disappear if I click on the “Game” window, or select a different aspect ratio. I even tried to delete everything (scripts, materials, plugins etc) and leave only the scene file but the problem persists. I am using windows 7 and running the x64 editor.

Thinking of sending a bug report.

The bug is confirmed by the tech support in my email, it is fixed in the latest beta.
