When I add a button element into the scene, it fills the entire Editor View window with this graphical glitch. It makes designing User Interface completely unusable.
Steps to reproduce:
Thank you!
Are there any error logs in the browser’s debug console?
Hmm… I can’t reproduce this on my test projects
Can you share a project that this happens in please and also what OS you are on?
Upon revisiting the project tonight, the issue has magically disappeared.
Weird!
Apologies for flagging a heisenbug
If it helps, it looks like you’ve somehow managed to apply a font texture atlas as an image in the scene which shouldn’t be possible 
Hi @Lozmosis ,
The glitch is coming from the Uranus Editor SDK running and preloading assets to make them available in editor scripts.
If you disable the extension, it won’t happen anymore.
Ahh perfect - that was it
