Ashley C3 beta r252 has introduced bad jank in Android exports.
If I export my game from C3 r252 with Web Worker enabled, what Im seeing is periods of smooth jank-free game play punctuated by peroids of severe jank. I can play jank-free for say 30 secs, then there will be a period of 15 seconds where game play displays severe jank, then it will go back to jank-free gameplay.
Prior to r247 my game had some issues with mild but noticable jank. Changes you made to 'frame scheduling' in r247 bascially removed jank entirely from my game (jank ~95% gone Id say). C3 builds r247 - r251 have been brilliant: Android exports have had smooth jank-free gameplay. But r252 is a major step backwards, jank is back and much worse in my game.
In the release notes you say beta r252 introduces support for Web Worker mode in Android exports. I guess its related?
Ill be going back to C3 r251 for the moment.
