I have same problem. When switching to scene view while in play mode Unity freezes and scene view looks pixelated and corrupted. How did you solve the problem?
Thanks! I managed to solve the problem. I removed one 3rd party plugin and the problem disappeared. This problem started after upgrading unity, so this plugin is not working yet in 5.1.
Plugin is Quick Decals 2. I noticed on their forum thread one user raported similar issue, so I guess they are working on this matter.
sorry I couldn’t figure out what fixed the issue. I just removed a few assets and it started working. I wasn’t sure which asset it was that was creating the problem so couldnt post solution. But yes it’s probably quick decals 2, it’s one of the assets I removed.
