STEPS TO REPRODUCE 1. Be in Plasma 6 2. Make your panel floating 3. Move cursor all the way to screen edge near a Task Manager icon and click OBSERVED RESULT Task Manager icon starts to get dragged EXPECTED RESULT Task Manager icon activated SOFTWARE/OS VERSIONS Operating System: Fedora Linux 38 KDE Plasma Version: 5.27.80 KDE Frameworks Version: 5.240.0 Qt Version: 6.5.0 Kernel Version: 6.2.14-300.fc38.x86_64 (64-bit) Graphics Platform: offscreen Processors: 8 × Intel® Core™ i7-10510U CPU @ 1.80GHz Memory: 15.2 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics ADDITIONAL INFORMATION If I move the cursor two pixels closer to the panel, it works properly. So a horrible hacky workaround could be to increase the global drag distance. This is a minor Fitts' Law violation.
