Hi,


I'm having a strange issue using the new build, 2015.2.8.0.

On some devices touch in the WebBrowser have stopped working, while working fine on others.
There are no issue when using an old build.

The issue is observed on the following devices with touch:
Acer ICONIA Tab W500-C62G03iss
Gigabyte GB-AEDTK-SI
TERRA All-In-One 1009363

On these devices the webpages doesn't receive any touch events. With JavaScript I've tried listening for "touchstart" and "touchend" in the TabbedBrowser sample, but these are never triggered on the concerned devices.

The problem seem to stem from something in Chromium detecting touch devices (this is a guess).
Quite possible related to https://code.google.com/p/chromium/issues/detail?id=439914#c22

I've tried the Chromium commands discussed in the thread, without any luck.


I understand that this is a hard issue for you to reproduce without the given hardware, but maybe you have an idea how to proceed?

If possible, you can try to apply this patch to the Chromium source.

There isn't much we can do unless we have the device to look into. We can not apply the patch in the above link since the issue and patch seems to only apply to X11, not on Windows.

Yes you are right about X11, sorry about that.

I'll try to investigate the cause of the problem a bit further, and return to you.


Thanks.
