I recently switched from 5.1 to 5.3 for our project, and I got some issues with flickering elements in the UI. I've uploaded a gif of the problem: http://gfycat.com/QueasyDeadlyLangur As you can see, when I move the purple selection between the between the social buttons at the bottom, the logo at the top flickers with the FB or Twitter logo for one frame. Also two button prompts in the bottom left corner (the Space bar and the Esc button) flicker with some other sprite. My menu does nothing more than move the rect of that purple sprite around. It was working up to 5.1, and now it's broken. I've tried everything (Reimport All, etc.) to no success. Anybody suffering the same fate?
