@corfe83 Would it be possible to see the culprit by git-bisect? (I'm gonna bed soon and will reply tomorrow)

hajimehoshi commented 1 year ago

Oh, by the way, I assumed this is a regression, but is this correct? (i.e. did the same tab worked with 60FPS before?)

corfe83 commented 1 year ago

I know the performance has been slow on android for a long time (users complain UI is laggy, mostly). Battle tab and building tab are both affected by this problem. Later I'll try testing with some older ebiten v2 builds to see if it was better at a certain time.

hajimehoshi commented 1 year ago

Sure. I think I'll tackle this issue after v2.5 is released, as this is not a regression. (If this is regression, I'll prioritize this)

corfe83 commented 1 year ago

It's not a regression in 2.5, so tackling in 2.6 makes sense

hajimehoshi commented 1 year ago

Could you check the draw calls at the problematic scene by -tags=ebitenginedebug on desktops?

hajimehoshi commented 11 months ago

Is it possible to know the debug log at the heavy screen? This doesn't have to be on Android.

corfe83 commented 1 month ago

Sorry for the delay. I tried looking into this and I don't think it's a problem now, at least in my testing in 2.7.3. So I think we can close this issue now.
