Sounds like something Steam might be doing.
Wasn't Steam. I figured it out with a little detective work. At first I thought it was an add-on I recently added. I usually favorite the most recent ones so that I know if there is a problem which ones to delete first. Wasn't that and I just resubscribed to them when I was sure. Turns out going full screen does it. I thought I could just ignore it but having my window disappear every time I click on something, even if its just for a fraction of a second, is really annoying. What was more than annoying is that it also made my OBS freeze and not update (whether I was making a video or not.) So I went back to windowed mode and that fixed the issue! Doesn't actually matter what my window size is, just clicking on it fixed the issue. I selected the largest window size I could (my monitor resolution is 1280x1024, on both screens actually, and setting that in windowed mode causes the program to automatically choose 1264x985- odd resolution I know but it works well, no more flickering of the SE window and OBS no longer freezes either, although the odd resolution causes it to place small black bars on the right and bottom of the video window.)
By the way did you know you can actually put ships in an ATV mode and can actually climb mountains with it just like a 4 wheel can do? I set the speed to 0.32 m/sec to do this!
