There is animation lag while opening and switching apps. It’s not there always but like 5 out if 10 times. it feels like its dropping frames. We tried alot to fix this issue and found that it’s something related to gpu. Increasing gpu minimum frequency from 260 to 338 reduces this quite alot but it’s still there. This issue is only on android pie, oreo runs just fine.
Here are systrace and SurfaceFlinger dump
GSI used: Pixel experience pie, almost all pie based gsis by phh - gapps version.
