Monitor Blacking Out for ~10s when ALT+TABing

When I alt+tab out of games like Beyond All Reason or Minecraft (Only when shaders are installed, doesn't happen in vanilla unmodified) my monitors black out, used to both of my monitors would go black for like 15s or so before the new window would take focus. I messed with some setting in both the Nvidia app and in Windows settings and now only the monitor with the game goes black, but everything else still lags while the switch is happening. Also, I have HDR enabled, but in games where this is an issue the HDR only takes effect in the game when I'm alt+tabbed \*out of it\*. Particularly annoying because I can only see the game in HDR when I'm \*NOT PLAYING IT\*. I play everything in borderless-windowed, and it's not a bandwidth issue from the DP cable, I switched from the cables that came with the monitors to a 16K UGREEN one I have and the problem persisted. Both monitors are 34" MSI MAG OLED ultrawide panels. I appreciate any help I'm offered.
