Beta 3.3 (724) Zoom Rotate Pan

[Andreas Raninger]

Zoom Rotate Pan is not as fluid as it used to be. It's more like 60fps than 120.

It looks fine for me (I have a 2018 iPad Pro), I mean it looks the same as the 3.2, I don't know what it could be!

[Andreas Raninger]

I have the second generation (2017) iPad pro 12.9. More fluid in 3.2 for me. Strange.

[Andreas Raninger]

I might have found the origin of the problem.
If I close the app with my image open and then launch the app, it happens. If I close the image and reload from library it's fluid again.

I just tested it and yeah I can confirm the issue!

Indeed, it is sometimes not smooth, i will try to fix it asap

[Andreas Raninger]

Works! 
Really strange with the panels slowing down the canvas gesture orientation. I wonder if that is a bug in iPadOs core?

Mixing uikit views with metal view can be a problem, it is hard to say…

[Andreas Raninger]

Drawing on top of the metal view will probably slow down metal as it probably have to wait for the UI to be finnished. I'm probably totally wrong. Modern systems would use some kind of an video overlay technique to solve that problem in hardware. I have to start coding again, I got curious. Time to download Xcode and do the "Hello, world!" for starters.
