It seems that the wacom tablet is unavailable with TE-India team. Hence, adding label TE-NeedsTriageFromMTV for further investigation.

Thanks...!!

So that we have all the context from the internal bug this was forked from, can you attach the output you get when interacting with this app using the tablet:

https://chrome.google.com/webstore/detail/pnacl-examples/mblemkccghnfkjignlmgngmopopifacf/related?hl=en-US


In particular, in the internal bug you were previously reporting output along the following lines using the tablet:

Mouse event: modifier: button:None x:200 y:142 click_count:0 
time:43959.2 is_context_menu: 0 


By contrast, using a mouse you were getting the following output:

Mouse event: modifier:left-button-down  button:Left x:60 y:116 
click_count:1 time:44144 is_context_menu: 0


Specifically, the former lacks the button and click_count fields, which suggests that at that point it was not generating the right input events. Are you still seeing this discrepancy?

I see the issue with Google Docs as well. Sheets & Gmail in particular.

Chrome: Version 60.0.3112.101 (Official Build) (64-bit)
Mac: MacOS Sierra 10.12.6

Likely the same as  issue 757069 

In response to comment #3:

At the moment, both tablet and mouse give rise to both button and click_count fields. So, I don't see that discrepancy.

Rather, the problem I see is exactly as described in  issue 757069 :

To have Wacom Intuos Pen clicks registered by Google Chrome, the first click in a browser tab has to come from a second device like the magic mouse or a trackpad. After the first click, the Wacom tablet clicks are also registered. This is true for each separate browser tab.

Thanks!
