Chrome for Android - Highlighting sticks around after touch #164

Closed Jaybuz closed 11 years ago

Jaybuz commented 11 years ago

This happens in Chrome Beta (31.0.1650.11) and the current stable version (30.0.1599.82).

Here's a screenshot. The blue clone of the button is the highlight left over from touching the button. It's static unlike the content, so it moves around strangely.

Can anyone else replicate this?

More importantly, can you replicate this with a reduced test case that uses an unstyled button? It might be related to hardware accelerated compositing, depending on the style applied to the button.

After a little bit of digging I've found that the highlight floating is caused by it's parent being scrollable (overflow: scroll;).

That's most likely a Chrome bug if anything. (https://code.google.com/p/chromium/issues/detail?id=305597)

I did find that if I removed cursor: pointer; the highlighting doesn't appear, which is probably to expected really.

The highlight sticking around is still caused by fastclick though. See: http://codepen.io/anon/pen/upiBy
