I've been using experimental build on my Antergos (Arch based) for a while and I've noticed that when I Alt-Tab from Unity window the text disappears from UI elements like buttons. After it disappears when I click it in Hierarchy it comes back again. My kernel version: 4.1.6-1-ARCH I'm using nvidia 352.41-1 driver on GTX 750 Ti
Same is happening on Ubuntu 15.04 x 64 - Nvidia 750ti Also, Artifacts of operations remain on the screen (like dragging a prefab to hierarchy window and canceling the operation results in a blue drag line remain on screen)
