testcase 1 of 2 (flash) - Status bar box becomes transparent.htm

Details 
>>>   My Info:   Win7_64, Nightly 45, 32bit, ID 20151127030231
STR:
1. Open "testcase 1 of 2 (flash)"      in a new tab
2. Open "testcase 2 of 2 (status bar)" in a new tab next to the tab opened in Step 1.
3. Switch to the tab with "testcase 2 of 2"
4. Wait about 3 seconds (in order not to experience another bug)
5. Hover mouse over the "Sample link"   [make sure there's a relatively long tooltip at the bottom]
6. Switch to the tab opened in Step 2.

Result:       
 The status bar blinks (first disappears, but then quickly appears-disappears) during the tab switch
 Bottom part of the flash plugin is cut off. It's also reproducible with "position:static" if
 you scroll the page so that Flash was placed under the status bar.

Expectations: 
 Status bar should just disappear. Flash shouldn't be cut off.
I am unable to reproduce on Mac.
OS: Unspecified → Windows 7
Hardware: Unspecified → x86_64
STR_2 (just read it)
 1. Open "testcase 1 of 2 (flash)" in a new tab
 2. Press Ctrl+Shift+R to refresh tab w/o using cache.
Result:
 Sometimes the message "Transferring data from bugzilla.mozilla.org" is displayed in status bar,
 and sometimes it clips a part of Flash content   (the same result as in STR in comment 0)


I actually tried to create a page with both flash content and a link, but it appears that the status bar is placed _under_ the flash content. When it's placed above the flash content, I encounter this bug. Filed bug 1229455 about that weird case

I think this might have something to do with the way the compositor currently waits on confirmation for plugin window updates from CompositorChild. It should wait on a sequence number here [1] vs. a boolean. I'm guessing with the rapid tab switching this triggers that flag is getting out of sync.
