Outside of logging out for 5-15 minutes and resetting your User Interface, that’s all I can really suggest. Logging out for a bit seems to show the most positive results from the reports I’ve seen, but obviously that isn’t helping everyone.
These reports are being looked into, but I would recommend adding to any current posts in the Bug Report forum. That allows our QA team to get more samples and a sense of volume, which can help them track down whatever might be happening.
