I have this issue too, on macOS 10.12.1 and with a Wacom Bamboo graphics tablet. Mouse clicks get through fine, but "clicking" with the tablet's pen doesn't work inside Flash content. Pointer movements are behaving as expected.

laforge@ would you mind looking into this issue? It seems this is an injection in M55, since it was working in M54. 

Krishna, could you get one of the testers to bi-sect the issue?  Adding components for both Flash Player and Input (Touch Screen).

+pbommana@, could you please bisect this.

In order to bisect the bug we need one of the external devices i.e., Wacom CTT-480 or Wacom Bamboo graphics tablet which aren't available with Test team.

If anybody has one of the affected devices and a chromium checkout, here are the instructions to bisect (scroll to bottom)

I am using an HP Chromebook and my Wacom Intuos tablet. I can no longer use flash content with it, and even Little Alchemy (http://littlealchemy.com/) seems to have a problem with it after a little bit. It seems to drag the picture instead of the element.

I have the exact same issue, using Wacom Intous CTH-480, Windows 8.1 and Chrome with web application from Mybalsamiq.com. As I am not a developer, I do not understand the "bisect" instructions. Can we help in any other way? Pls fix this urgently as I am using this as my main work tool.

We have also noticed that the latest version of Chrome for Mac has this Flash issue with some of our SMART Board products (Interactive White Boards and Interactive Flat Panels)

We will bring up some flash content, such as http://www.online-stopwatch.com/countdown-timer/ and using our Board we can not click on any of the Flash content buttons. If you take focus off of the Chrome Window and then quickly double-click on one of the Flash content buttons then it will actually trigger it, but again it has to be a double-click on the same object and only one at a time and then you have to repeat the process if you want to click on any other flash content object.

So is this something that will be fixed or with Chrome starting to block Flash content will this simple be ignored as flash will soon no longer be supported by Chrome and therefore no Flash related bugs will be fixed?

Thanks.

Can someone help us in identifying the regression by trying a bisect (finding out the chrome binary which hit the issue)?

Tested the same by playing the game Kancolle on win7 and win10 - Works fine

As per comment #13, Can anyone try bisecting the issue as Test team doesn't have the specific device (Wacom CTT-480 or Wacom Bamboo graphics tablet)

Hi also having this issue with osx + Wacom Intuios 3 no click throughput at all into flash. 

Broken in the latest public chrome on osx - 55.0.2883.95 (64-bit) But working as expected in 57.0.2983.0 canary (64-bit) - I am presuming this will become public at some point - if you need wacom support it might be that you swap to upstream canary builds until the latest stable catches up. 

I can confirm that Canary version 57.0.2983.0 64bit fixes the issue on macOS.

I have also confirmed that using the Canary version of Chrome fixes the Flash content issues we are seeing on our SMART Board products. So when can we expect these changes to make it into the next public release update of Chrome?

I can confirm that Chrome 56 fixes the issue for us (using SMART Boards.)

I just updated from Chrome 54 to 56 after purposely keeping it on 54; I can confirm that Chrome 56 fixed 55's issues with tablet input devices with things involving flash.

as per #21

Wacom tablet does not work with flash-based web applications,
All ready try to update everything, from flash to wacom drivers, to chrome, and it still does not work.
