Reported 2010-07-15 01:53:15 PDT

Clicking in the flash content doesn't work - when pressing the mouse button, the cursor changes from a pointing hand to the arrow (which is wrong btw) and releasing a button doesn't do anything - for example try pausing the video on youtube - clicking on the button in the flash window just doesn't do anything. The same in the Flash preferences dialog. It looked like the problem was only triggering after opening a context menu (i.e. right-clicking) on the flash content, but after pulling the latest Qt 4.7 I can reproduce it right away by just loading the youtube web page.

Confirmed on ToT + current Qt 4.7. Sometimes it works, sometimes it doesn't. Definitely needs to be investigated.

It seems this is due to a bug (or rather, new feature) in GDK. We need to put GDK in backwards-compatibility mode for Flash to work properly on Linux. This is accomplished by setting the environment variable GDK_NATIVE_WINDOWS to 1. Chromium does this, Firefox does not.

Comment on attachment 62036 [details] Proposed patch Grrh.. this patch makes the session's first Flash file loaded audio-only. Thinking about it, perhaps working around this is outside the scope of QtWebKit.

This is an issue with a specific plugin (Flash) and can be worked around in user-agent code. Let's try to avoid adding to the pile of Flash-related hacks in QtWebKit.

What I meant was "browser" :) Make your browser code set GDK_NATIVE_WINDOWS=1 in the environment and you won't have this problem.
