Thanks, I pictured what you were saying just don't know what to do about it. I have never seen this issue before.
As I said I run full panel. This doesn't make everthing full screen either unless it is maximized or set to be full screen, otherwise it just centers. Have you tried this?
Another thing I have noticed in fact it just happened to me again after last months roll-up update in Windows,
after the update my monitor driver is back to being the Generic PNP, I then have to reload my manufacturers driver. In my case, the PNP driver messes up FreeSync. So you might check this, or if you never had a Manufacturer Driver installed to begin with it could potentially help, even if not with this issue, something else.
I have also seen where the settings in the monitor itself can affect things, and many of the weird things going on causing issues in current drivers is because Microsoft has been sneaking in new standards upgades into their updates. So for for instance many monitors have settings for the different levels of Display Port Standards. You might look into the settings you have, as something that once worked might now be an issue. I even had an monitor once that would mess up and you had to unplug it and let it discharge and then turn.
Also give another port if available a try on your card and monitor. I have seen ports just go bad out of the blue. I have a bad HDMI port on my last R9 380x card.
If none of these simpler things don't pan out, I would move that monitor to another computer and see if it is fine there and/or vice versa try another monitor on yours to trouble shoot the issue. At least you will now for sure where the issue definitely resides.
If you don't have that option, unless your mean to your neighbors or family members, someone will help you out.
Good Luck! Let us know what you figure out.
