Automation problems since LP11

So I have one plugin in particular that is an AUv2, that no longer automates correctly since LP11 (specifically parameters get "stuck" or move in rough, jagged steps even when the line is smooth). I am also experiencing stuck parameters with other plugins although I've been so focused on this one plugin in particular that I need to collect more information on which ones exhibit similar behaviour.

My question is, has anyone else experienced this? Does anyone know what might have changed in 11 that would cause automation to no longer function correctly for an AU? FWIW the only way I can get the plugin in question (Reason Rack Plugin) to work correctly is to disable sample accurate automation in Logic. But I don't want to do that. The developers, Reason Studios, are aware. But so far they have no ideas.

Interested to see if anyone else has experienced this. Thanks!
