UI text disappears in Editor after switching to another app and returning to Unity

In Unity 5.1.0f3 on OS X 10.9.5, if I switch away from Unity to another application then return to Unity, all text in UI elements will disappear (sometimes immediately, sometimes after half a second or so), in both Scene and Game windows. If I resize the Scene/Game window, the text will immediately redraw.

Anyone else have this problem? If it’s not just me, happy to file a bug report.

I get this too. It’s Mac specific as I’ve tested it on PC and it doesn’t happen there.

Me too.

Weird, mine happens in Windows.

Still happening for me too.

Literally any time I tab to another app and back, the UI Text is gone and I need to move something or disable/enable something to bring it all back.

Windows 10 - Unity PRo

It happens to me sometimes too, I think it’s a Unity refresh problem.

This is an old problem doesn’t rlly get fixed
Also pink images not just text

I get refresh issues as well – text not being rendered correctly, and scrollrects getting corrupted. On a PC running Windows 10.

Doesnt matter if you’re running windows 7, 8 or 10
This issue is very old and has been there for such a long time. Early 4.6 I think already… when the UI came out.
Its not an issue for the actual build though and thats what is most important.
Quickfix is just pressing the play button or resizing the game window and it’ll refresh because of a canvas update

My guess is that the garbage collection is picking up those meshes and then throws them away when you return you see weird artifacts because it is pointing to a space in memory which is in use by something else and tries to make sense of it… thus being “corrupted”
