1354154 - Flash content enlarged enormously erratically

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

Attachment: blackend flash box on mlf account.jpg

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170323105023

Steps to reproduce:

I opened and played for some time my game accounts on
http://www.mylittlefarmies.de/game/.
If you want to reproduce, please use the following login details in the login banner on top of the site of one of my game accounts:
username: samweis10
passwort: obafmkm


Actual results:

Playing for some time, the flash content played in the center box erratically turns black (see screenshot attached) or shows other game content enlarged enormously. Presumably the black windows is an enlarged black spot in the game as well. The enlarged spot seems to be one somewhere from the upper left corner of the center box (the viewpoint?).

This bug occurs erratically. Sometimes you won't see it for a long time (> 10 minutes), sometimes you see it every three seconds.


Expected results:

This should not have happened and is verified not until on FF 52.0.2, with or w/o addons loaded on startup, with or w/o other tabs or FF windows opened, and with FF only. Flash player version is 25.0.0.127.

You can kind of workaround this bug (but you have to do it each time it occurs) by switching to another tab and then switching back.

Rainer, it appears you're using the 64-bit version of Firefox? Have you tested the 32-bit version also to see if it reproduces there?

Would you be willing to try this again with 64-bit nightly builds (nightly.mozilla.org)? We have been working on a new rendering interface with Adobe and it's turned on there.

Annotations on Firefox Nightly 55.0a1 (daily updated) (64-bit)


(Original installation in a folder of its own, using a profile of its own, w/o addons, on a fresh installed Windows 10 Pro 64-bit [2017-04-11: w/Creator's Update], Flash player 25.0.0.127 + 25.0.0.148, testing environment: Intel core i7 notebook)

A Firefox 32-bit has not been tested.

Differences compared to Firefox 52.0.2 (64-bit, w/ or w/o addons), on same machine, tested for several days:

(1)  Website https://www.mozilla.org/de/firefox/nightly/firstrun/ at Firefox's first run:
      (a) button "Start testing": the link is broken (https://oneanddone.mozilla.org/);
      (b) Nightly User badge link https://badges.mozilla.org/badges/claim/vpvacp leads to an XML document, not revealing
          how to actually get this badge;
      (c) opening the link https://www.facebook.com/mozilla.de slows down the browser hugely, eventually displaying a script
          notification.

(2) No more random enlargements in the Flash window. However, there are other issues:
      (a) Sometimes the game characters or buildings have their information dialogs displayed in the upper left corner (see
          image NIGHTLY_1), rather than centered. Particularly with the buildings dialogs, they tend to be not reachable 
          with all of their functions (see image NIGHTLY_2).
	  This issue seem to occur sometimes with other tabs running.
	  Workaround: Close game and relaunch.
      (b) Flash loading and playing is sometimes slowed down slightly, around one quarter. And there is an occasional delay
          in moving the visible clipping of the game (done by pressing and moving the left mouse button).
      (c) The Windows taskbar shows a second hidden window of the Nightly, which can be closed, but not be displayed (see 
          image NIGHTLY_3).

(Note: All images had been downsized to save bandwith.)

Hey Rainer, sorry for the delay in responding. Are you still seeing this bug? I'm betting the issue is fixed in the latest flash release.
