Many (all?) Android apps render their frames to the screen in almost correct order, resulting in very weird choppy and jerky user experience, even though the frame rate is high.
- Install e.g. Firefox, Vivaldi, Here WeGo
- Firefox: Start scrolling a long web page (flick and let it scroll until it stops)
- Here WeGo: start navigating to an address
- Smooth screen updates
- Oddly jerky screen updates, with high framerate still
Judging by the web page scrolling, it looks like some frames get rendered in incorrect order. It’s not a showstopper, but it really brings the user experience down.
This is easy to see once you know what to look for, but I’ll try to get a friend with a fancy Android phone with slow motion capabilities help me out.
