    Description

      I've discovered that on Xiomi Mi 10T Pro (Android 11) animations starts to run twice (or more) faster. Initially it might run OK, but just after touching screen it starts to run ~2-3x faster! Sometimes it runs faster from the start, so I guess you have to "give device rest", launch application (via QtCreator) later ans then touch screen to reproduce. Maybe something with power management, CPU speed or whatever..?

      See video attached. I've used test application which is attached too.

      There's no such issues on any emulators, or on real HUAWEI Mate 20 lite with Android 10, or some old Sony Xperia Z with LineageOS (Android 8.1).
