I am updating Level With Me and Unicycle Hero from 3.4 to 3.5 b9883. Now actors that rotate seem to do a sheer/shift when nearing 0º. I have attached 3 videos, 2 from me and 1 from Colin Lane, showing the bug. I assume it happens on smaller actors but is only noticeable on larger actors. I made no changes to these actors or the scenes besides updating to 3.5.

I'm not seeing any issues in my rotating square test on Flash/HTML5/Windows.  Is this problem exclusive to iOS?

Sorry, yes, iOS.

I wonder if this is related to the jittering issue that was also reported.

Seeing this also in build 9895.

The actor rotates back and forth fine in flash, but shears and snaps on iOS.

Is there anything else you need from one of us in order to help solve this one?

It might be an OpenFL issue if it's only affecting iOS.

So...Do I need to approach the openFL community at openFL.org and describe this problem? Is there someone specific I should talk to?

I've never reported anything to OpenFL so I wouldn't know.  I tried looking for this issue on their forums and github but I wasn't able to find anything.

Just an update, this glitch occurs at every 90º that an actor is rotated, not just near 0º.

Would any of these two threads at openfl.org have something to do with this bug? I don't quite understand what they're referring to, but it sounds like this bug. "It looks like the shape is shifting one pixel to the left/right/up/down occasionally."

Is there any way we can prioritize this? I am dead in the water until it is fixed, and it looks like it will affect any iOS game with rotating actors. Do I need to post in openfl forums? It would probably be more clear if one of you posted, since you are smart.

I'm very sorry, I'll look into this beginning tomorrow.

Not yet. I've confirmed that this is a problem in OpenFL and not something we're doing in Stencyl. I've asked in the OpenFL discord, and while another user has also seen the bug, the lead developer can't reproduce it (doesn't happen on iPad Air apparently). So I'm trying to investigate further and see if I can fix it myself.

Cool update and play around with it when I’m done traveling.
