Weird persistent UI glitch in UPBGE 2.5 (Blender 2.79.7) (only in one .blend file)

Hi
I’ve been using Blender for ages and I’ve never run into this issue before. I’m working in UPBGE 2.5 (based on Blender 2.79.7), stuff looks broken and icons disappear.

What’s odd is that once the problem appears in this .blend file, it persists even if I create a new scene or reset to factory settings. The only way to make it go away is to completely restart Blender. However, as soon as I reload this particular project, the issue comes back. In some cases, the problem temporarily disappears on its own, only to return later.

I know this description isn’t very helpful, but I hope someone has already encountered something similar and managed to solve it.

(I also don’t feel comfortable sharing the .blend in question, but if I manage to reproduce it in another way, I’ll add it here.)

I also have my doubts as to whether this is a problem related to Blender itself or just to upbge, but since this is the first time I’ve seen it and I’m using upbge, I decided to post it here.

I believe (and hope) that I have found a fix for this issue, and it’s quite simple.
You basically reload your project, but disable the “Load UI” option (on the file selection screen). This will discard all the changes you made to the viewport, and apparently, it also eliminates the glitches.

It’s been about 2 hours since I enabled the option and reloaded the file, and so far the problem hasn’t happened again, so I’m confident this is the solution (and if it happens, I’ll just reload it again).
