Latest Chrome update 49 causes animation jitters (scale)

[dada78]

Hi guys,

I have a simple scale animation going and it passed QA through all browsers. Smooth animation. Looked beautiful. However when I checked today the same animation looks super jittery on all scaling elements in the latest Chrome update.

 

I noticed that on my machine Chrome updated to Version 49.0.2623.87 (64-bit). I also checked on a colleagues machine who also displayed the same jittery animation. On anther machine however that uses the previous Chrome version (48) everything looked as smooth as in latest Safari and Firefox.

 

I will post a codepen a bit later but for right now the code is:

 

.set(bgr,{scale:1, transformOrigin:"right top"})
.set(woman,{scale:1, y:-9})

.from(bgr, 8, {x:80, rotationZ:0.01, force3D:true, scale:1.3}, "start")
.from(woman, 6.5, {y:20, rotationZ:0.01, force3D:true, scale:1.3}, "start")


//I probably don't need the force 3d anymore but left it in there. No difference with or without I don't think..

Ah thanks OSUblacke. Yeah Carl's demo illustrates this perfectly as per your post. Just wanted to call it out here once more:

When i was testing

, from the post Blake linked to above. i didn't see the pixel snapping on Apple iOS Chrome 49 (tested on a iPad Air 2). I guess it is only on Apple Mac Chrome 49.

I see it on Win10... but does anybody even know where this change is in change log, and if it is going to be in the next versions?

Interesting Blake ..

 

So it looks like the pixel snapping is only happens on:

• Windows 10 - Chrome 49
• Apple Mac - Chrome 49

But it doesn't happen on

• Windows 7 - Chrome 49
• Apple iOS - Chrome 49

If anyone else sees the pixel snapping please let us know, Thanks!

Hi guys

 

yep , i see that on Win 10 too : Chrome Version 49.0.2623.87 m (64-bit)

Yep, seeing it in Chrome 49 on Windows 7 at home and on a Mac at the studio. I first noticed it on The PC then once I got to work I viewed the same site just prior to Chrome updating itself, silky smooth, then there it was.

Particularly noticeable on fonts!

So looks like Chrome 49 new flicker and pixel-snapping bug is affecting:

• Nvidia dedicated graphics cards
• and some Intel integrated graphics cards

Others are reporting the same on this similar forum topic:
