However, Qt Widgets apps, like Dolphin, and original Qt Quick apps, like Telegram Desktop, are very smooth when resizing window. STEPS TO REPRODUCE 1. Open Discover or Filelight 2. Resize the window quickly (bottom right corner) 3. See if the sidebar and toolbar are shaking (in theory they should not) OBSERVED RESULT All UI parts are sharking https://www.youtube.com/watch?v=FY5QE_Lxo2I EXPECTED RESULT At least sidebar and top toolbar shouldn't shaking, like Dolphin or Telegram Desktop SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20240410 KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.7.0 Kernel Version: 6.8.4-rc1-1-default (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 5600X 6-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: Micro-Star International Co., Ltd.

Unfortunately this is a fundamental flaw in QtQuick itself that can only be solved by the Qt people. They're aware of it but as you can see, it's not fixed yet. Telegram isn't affected because it's not actually a QtQuick app; it's using custom QtWidgets stuff.
