I have all my fences rolled up, but when I run a full screen game at a lower resolution it sometimes cause the my fences to not return to the correct position when I return to the desktop. This only seem to affect the fences at the bottom of the screen. Throwing together a quick mock-up in Paint to illustrate.
As you can see, the title is where it wold be if the fence was open, when the fence is closed. If I mouse over it it rolls down towards the bottom of the screen. For the record, I have multiple screens, but only one of them have fences on it. This sometimes also happens when I turn of the TV, which is connected to the computer via a Surround Receiver. The screens are as follows:
- 4k Monitor
- FHD Monitor
- FHD TV via Surround receiver
