STEPS TO REPRODUCE 1. Use a high frame rate Monitor (144hz in my case) 2. Activate double click to open files and folders in the "General Behaviour"-Settings OBSERVED RESULT You need to double click extremly fast with files located on the desktop. (the higher the refresh rate, the faster you have to double click) EXPECTED RESULT The same click speed as on Dolphin.

Unless debian is backporting fixes, you're unlikely to get a bugfix since 5.20 isn't an LTS release. There is debian 12 with Plasma 5.24. https://repology.org/project/plasma-desktop/versions#debian_11
