Now I tried the same app on my friends PC (Ubuntu)- and it works great.
On my Windows 10, Dell, intel i7, 16GB RAM it is jagging -

your config above is Good Enough. Normally Qt requires min 4GB and 16GB will be enough to run any graphics. when you say intel i7 what's the processor speed.
You should check if any background process keeps windows busy in providing priority to your app. normally windows OS guarantees for more than 20ms.
if its over please mark solved. or any questions you can ask?

@Witc This does not answer the question which compiler you're using as you installed Qt for ARM64, MSVC2019, WebAssembly, Android and MinGW...

I am using Qt along with python 3.10 + Pyside6. No any line of my code is written in C/C++ ...

Tried it on Qt 5.15, and it works perfectly
