Hi,  
I just updated from 3.16.2 to 3.17.0 and in my prepared game I noticed some weird shaking of sprite on some devices… looks like this… tried everything to solve it but with no lock, can anyone help me with this?  
3.16.2 is not affected with this… [https://www.youtube.com/watch?v=BkjzM62E6oU](https://www.youtube.com/watch?v=BkjzM62E6oU)

I’m using cameraDolly updated by position of player sprite which is followed, nothing special.

what do your x,y values look like? are they jumping between float values? does it only happen when you are moving the whole camera and not when you move a single sprite?

It’s round numbers (also tried floats), it’s happening only on mobile where pixel ratio is 3 and only when camera is following… if camera is static it works fine, any ideas?

Do you still have this issue?  
Can you share your code?  
Can this bug be reproduced in the chrome dev tools with a DPR of 3? Or only on a mobile device with DPR \>= 3?  
In 3.16.2 everything works fine?
