There is exactly 1 program that is having this issue. Every other program is working perfectly fine.
Regardless of how many times I close this program or restart my machine, this windowed application can only appear in full screen. What's worse, it does not respect my show launcher settings. Using Alt + Space I can get the window dropdown to appear, but regardless of whether I click Maximize or Unmaximize, it doesn't change or move a bit. I can move it to another workspace via this menu, but in every workspace it renders the same (full screen, hiding the launcher, cannot be moved with Alt + drag). I have tried disabling / reenabling Unity (no effect) and have window decorations set to off.
The last option is to uninstall and reinstall the program, but I'd prefer to not have to do this. If anyone has any idea, please do share!
