SUMMARY STEPS TO REPRODUCE 1. Move any window from the title bar to top for maximize or side. OBSERVED RESULT If I open a window and move it from the title bar to the top of the screen to maximize it or to the side so that it occupies half of the monitor, the computer keeps a few seconds (10-15 seconds) frozen and then everything goes well. I HAVE OBSERVED THAT THIS HAPPEN WHEN I USE MY MONITOR NETBOOK. IF I USE A EXTERNAL MONITOR THIS DON'T HAPPEN. My netbook is MSI GS75 and it have Nvidia Optimus (RTX2016 + Intel).I have installed nvidia drivers propietary and selected nvidia card in prime profiles. I like workaround this run if i disable compositor. EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE NEON 18.04 (available in About System) KDE Plasma Version: 5.16.1 KDE Frameworks Version: 5.59.0 Qt Version: 5.12.3
