There is a problem with multi-screen and kscreen. When I connect second monitor(1920X1080) there is no screen problem with extended config, only my touchpad get crazy, and get much faster so I can't control it. If I close lid, second monitor is great, go to normal resolution and touchpad slow down at usual. When disconnect hdmi monitor panel stay there, there is no way to force it to get back to laptop's monitor. I only can do to reconnect monitor and delete panel, disconnect monitor and on laptop's monitor create new. Kscreen also get full resolution of screen when go to fullscreen, without getting smaller for panel's width and height.

Reproducible: Always
