Please describe your issue in as much detail as possible:

After the last update to the stable client, when I exit BPM to small or large desktop modes, the desktop modes appear 2 to 3 times their normal size. The only way to fix it ts to restart steam in one of the desktop modes and avoid entering BPM.

Steps for reproducing this issue:

1. Start steam and enter BPM
2. Exit BPM
3. Look at the size of the desktop modes

Things I've tried:

1. Rebooting PC.
2. Setting the desktop to 100% scaling instead of the 200% I normally use on my 55" 4K tv (recliner is 3 meters back).
3. Starting steam without the -forcedesktopscaling 2.8 switch I normally use on my 55" 4K tv.
4. Disabling GPU accelerated rendering and hardware video decoding.
