I have the following issue:
Some large animations using react-native-reanimated and involving animating padding, height and transform are flickering when sentry is enabled, setting enableStallTracking to false in Sentry.ReactNativeTracing options solves the issue.

Steps to reproduce:
It's unfortunately hard to create a minimal reproduction example. The bug only appears on complex animation involving height and or padding, I'll try later if I can isolate a more specific reproduction case.

Actual result:
Those animations are flickering/jerking

Expected result:
No interferences between reanimated and sentry

@fdecampredon Thank you for the message, I understand that it's difficult to reproduce.

Could you share some example animation, where you are seeing the flicker, event if in new app it works it might help us debug the issue.

Does this affect animation driven by JS or by native or both? As disabling stall tracking helped I would assume the JS drive animations are affected.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!
