Bug report:? UI problems

When interacting with a lot of different vending machines or consoles in game, I’m only getting a blank white window. I’m not sure if this is a shithouse internet problem or a bug.
Any suggestions?

Typically when I run into this I just wait a bit with my mouse on the window and it eventually pops up.

as an example, this was after i opened the controls for a valve

This happens if you modify the size of the window AT ALL. Windows are not resizable, scroll to the corner and attempt to resize the window. If not restart byond

That seems to be the fix, have had zero problems since then.
