Nvidia GTX770, proprietary driver 346.59 (recommended in Ubuntu), Ubuntu Vivid. There was no such problem on the same hardware in Ubuntu Trusty with KDE 4.14 Everything can be seen on the video in url. Reproducible: Always Steps to Reproduce: 1. Open systemsettings5 2. Open some configuration modules and switch tabs Actual Results: Sometimes there is a graphical lag before displaying settings. Expected Results: Settings should be displayed smoothly
Is this something you can reproduce with Plasma 5.19 or 5.20? I don't get any lagging anywhere.

From #481207 Iyán Méndez Veiga 2024-02-11 12:11:19 UTC SUMMARY While navigating through system settings, some options take a noticeable amount of time to open. For example: - In Windows Management, "Windows behaviour" and "Task Switcher" open fast, while - "Desktop effects" and "Kwin scripts" are two or three times slower STEPS TO REPRODUCE 1. Try on a clean Plasma 6 session 2. Open System Settings 3. Try to open different options. For example, the ones mentioned above. OBSERVED RESULT Some settings take quite longer than others to open giving a sense of lagging to the user EXPECTED RESULT All settings should open fast and smoothly like in Plasma 5.x SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.93.0 KDE Frameworks Version: 5.249.0 Qt Version: 6.7.0 Kernel Version: 6.7.4-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz Memory: 15.3 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics Manufacturer: LENOVO Product Name: 20XYCTO1WW System Version: ThinkPad X1 Yoga Gen 6 -------- smow 2024-04-14 01:33:37 UTC I noticed this awful slowness while opening "File Search" module. ___ Operating System: Arch Linux KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.7.0 Kernel Version: 6.8.5-zen1-1-zen (64-bit) Graphics Platform: Wayland
