Framerate drops in game after tab out

[NateP296]

Recently I noticed my monitor drops framerate after tabbing out of a variety of games (Destiny, Valheim, Apex). My monitor is 144hz and when this happens, it feels more like 40ish. The game itself reports normal framerates but even in the desktop, my mouse if clearly moving a bit more sluggishly. No settings on the system are changed from what I can tell and the only way to fix it is to restart my PC. Is there any way to prevent it from happening other than just not tabbing out?

Thanks in advance!

Normally when I have issues like that I tend to try and switching the full-screen to windowed boardlerless or vise versa. I have had issues with things not running correctly in fullscreen and switch to windowed boarderless fixed the issue. I have also had times where I had to switch to full screen to fix an fps issue.
