Details

Originally reported in this bug on a Mali-T830, but even on a high-end Samsung S20 Plus (Mali-G77) I see 100ms GPU time every frame when scrolling near the top. My OnePlus 8 (Adreno 650) is slightly better with only 30ms per frame.

On the adreno the profiler says it's mainly in "target init", whereas on the mali it's a mixture of "target init" and brush image.

I couldn't reproduce on desktop even after making the window narrow so that the content matches mobile.

Severity: -- → S3
