1405346 - Flash plugin on maximized browser in multiple tabs does not receive mouse events

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect, P2)

Description

[Dries]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170824053838

Steps to reproduce:

This only occurs on windows platforms, with firefox 55.x and flash content with scaled width and height properties.

- Open a page with flash content that has scaled width and height. I created a test app on http://www.tunify.com/tunify/testApp/TestApp.html
- maximize the firefox browser (not full screen, just maximized)
- open other tabs
- go back to the flash app.


Actual results:

You can't click the flash content


Expected results:

You should be able to click te buttons etc.

When the embedded flash has fixed width and height, there is no problem. I think it has something to do with rescaling the embedded flash content.

Hi Dries, 
Please tell me which versions are affected?

Comment 2

Hi Valentina,
We have reproduced the error on Windows in Firefox 55.0.3, 32bit version

Can you please tell me if this issue is reproducible on Nightly 58.0a1 and Firefox beta 57.0b4?

We could also reproduce the problem in the latest official release: 56.0 (32-bits).

It does not appear in Nightly 58.0a1 (64-bits) and 57.0b5(64-bits) (I could not find the 57.0b4 download)

Those last 2 versions are both 64-bits and the linked bug report by Kohei Yoshino mentioned that it only occurs on 32-bits versions. Are there also 32-bits versions of those beta releases?

When I use the 32-bits versions, the problem still occurs in versions 57 and 58. 

Tested with 57.0b4(32-bits), 57.0b5(32-bits) and the nightly 58.0a1(32-bits), occurred in all of them.

Only the 64-bits versions are unaffected.

The current flash 27 beta (which should be released here in about a week) should fix this bug.

[Liz Henry (:lizzard) (relman/hg->git project)]

Marking this wontfix for 56 since we expect the issue to be resolved by a new version of Flash.

Dries, are you still seeing this?
