MMB Move Scroll breaking MMB button in certain games on Proton

Figured I’d post in here because I’m not entirely sure if this is a KDE/Wayland/Proton issue and was hoping someone could help point me in the right direction. I’m having trouble with the “Press middle button and move mouse to scroll” setting. When enabled, it breaks all functionality with that mouse’s ability to be able to use the middle mouse button click in certain games such as Hitman WOA, and Sniper Elite 5/Resistance. It seems like proprietary engines are more likely to break while Unreal/Unity games seem to work just fine.

Any ideas on how to get these games to work would be appreciated as the scrolling feature is very nice.

P.S. I have tried with different verisons of Proton including 10.
