Created attachment 167998 [details] Demo showing the bug SUMMARY When playing a game on a multi-monitor setup, the mouse can escape the main monitor (Where the game is being played), but is teleported back to the window fairly quickly. The issue is that when it is outside the window, clicking (IE: Firing a weapon), instead causes the focus of the game to be lost, and the other monitors become the focus. What is interesting, is since 6.0.3, the game still looks around as if the mouse is still present in the game window. Pre 6.0.3, the mouse would move outside the window and the game would stop looking around. STEPS TO REPRODUCE 1. Play a proton Game on any version of plasma 6.0.x on a multi-monitor setup 2. Try to look around 3. Notice that the mouse is escaping the main game window. I've attached a video here to show the bug in action SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION
