Created attachment 166178 [details] The mobile theme that was enabled somehow SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** I am not exactly sure how this can be reproduced, anyway I turned on my computer after I came home from school today and I everything was normal at first but then after launching certain apps like, Enigma, TPT Ultimata, Minecraft, etc... there was no titlebar on the windows and I couldn't resize any of them. Another thing was firefox and any other app I opened (except the ones without a titlebar) would open in fullscreen. I found this bug on a video on Plasma 5.4. I later found the fix when I saw a Plasma Mobile theme activated and I instaed switched it back to Breeze. Oh yeah the video is this https://www.youtube.com/watch?v=VvJ-S3j1nyg STEPS TO REPRODUCE 1. Have computer shut down randomly I guess?? (I dont know I was at school when it shut off) 2. have a plasma mobile layout as your desktop somehow OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian 12 "Bookworm" Stable (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION Like I said I am confused on how this happened
This indicates that the system is misconfigured, and KWin fell back to the fallback window decoration theme, Plastik. I's recommend following up in a Debian-specific forum to learn how to safely customize the system. In the meantime, you should be able to switch to the default Breeze global theme to recover.
