I can't run the video here, but you might just have to lerp the zoom to pre-set numbers to have it working fine.

Are you doing a fading effect (layer effect or like lerped opacity) at the same time too perhaps ?

I figured it out!

It's the *text*!

Apparently if you zoom in too much when some text is on a zooming layer, the draw calls go absolutely bananas, and the browser will eventually crash! How nobody has run into this issue, I'll never know.

Thankfully I've been able to replicate it in a blank project and I'll be submitting a bug report.

Thanks for the suggestions everyone!

Edit: Here's a link to the bug report.

newt 60, for a smooth zoom. And does 'calling a zoom' have some kind of performance implication that I'm unaware of?

I would have suggested halving that while increasing the scale rate.

Im not sure thats all gpu there, and telling it to scale faster than it can be seen is pointless.

Then it could cause a bottleneck there too.

newt what do you mean? 60fps is 60fps and it will obviously be noticeable if scaling at any lower rate. Anyway that wasn't the cause of the problem.

Interestingly, I would guess the same thing would happen if C2 could render vectoriel files, as the texture will increase in size and be processed each time in that too. (Kind of offtopic but still)

Glad you figured it out...but are you talking about spritefonts, or actual text objects?

ahh yes Ashley warned against using Text objects when they are moving...apparently they create a tremendous overhead.

Glad you figured it out..
