[impeller] rendering, performance problems with impeller on PowerVR devices #161304
Description
Steps to reproduce
When running a Flutter app with Impeller on a Galaxy Tab 7 Lite (Android 14), the performance is really bad. Rendering stutters, crashes, rendering glitches. No problem at all without Impeller.
The device is a Samsung SM-T220, the GPU is PowerVR Rogue GE8320
It probably is something with all PowerVR devices, see this older bug:
Expected results
fast, clean rendering with Impeller
Actual results
crash, bad rendering, hiccups
