Other tweaks:

• Disabled Xalia for Rockstar Launcher - aftar a recent update it got native contoller support which resulted in registering events twice.
• Disabled Xalia for winforms applications (e.g. Imperiums: Greek Wars launcher) due to compatibility issues.

Note: Xalia is the open source tool that Proton integrates to give gamepad controls for launchers.
