Description Tom Horsley 2011-06-11 00:47:20 UTC

Description of problem:

http://digital.olivesoftware.com/Olive/ODE/FTUKDemo/ is one of the demos of
the software from the demos page at:
http://www.olivesoftware.com/demos/

If the demo works, you will get a table of contents on the left side of the firefox window and a image of the newspaper on the right side of the window (the image uses flash).

When I'm using the standard fedora 15 install with nspluginwrapper, the right side of the screen never appears (it can be in various random states from blank gray window to white with scrollbars that don't move, etc).

If I say "yum -C erase nspluginwrapper" and then try again (using the appropriate native flash-plugin so I don't actually need the wrapper to run flash), then everything functions normally.

Version-Release number of selected component (if applicable):
nspluginwrapper-1.3.2-1.fc15.x86_64

How reproducible:
every time

Steps to Reproduce:
1.see above
2.
3.
  
Actual results:
No newspaper

Expected results:
Newspaper.

Additional info:
https://bugzilla.mozilla.org/show_bug.cgi?id=663411 was the upstream bug I filed when I thought this was a firefox 4.0.1 issue, but the nspluginwrapper experiment clearly indicates it is not a firefox problem.

I see (or rather, don't see) the same issue using the wrapped 32-bit plugin on F15 x86_64. Haven't checked with the 64-bit plugin, so haven't tried removing nspluginwrapper. If I try flipping between tabs, or changing between single- and double-page mode, I can sometimes see what looks like a corrupted display. Could there be a video driver issue as well? Am using the proprietary Nvidia driver.

Just tested on a F15 i386 box and confirmed the behavior. Right side fails to display with nspluginwrapper installed, works after removing it. So it's not arch-specific. You can change the Platform to "All Linux".

Comment 3 Andre Robatino 2011-06-12 01:29:32 UTC

And I'm not using any proprietary drivers on the second machine, so forget what I said about that in comment 1.

Comment 4 Martin Stransky 2011-06-20 14:08:21 UTC

Yes, I can reproduce it although I have no idea why it's broken.

Comment 5 Martin Stransky 2011-10-20 15:18:04 UTC

Wontfix. Don't use nspluginwrapper, firefox provides plugin-container and flash is 64-bit too now.

Isn't nspluginwrapper supposed to be usable with other browsers besides Firefox? Also, there could be a bug in a 64-bit plugin (not necessarily Flash) forcing people to use the wrapped 32-bit version.

Not sure, but other browsers uses something like OOP (out-of-process plugins) too.

64-bit flash is supposed to be stable now.

Does this mean there is no longer any need for nspluginwrapper? If so, it should be retired. As of F16 it's still being included in a default desktop installation.

Which is why I added "not necessarily Flash". (Besides, 64-bit Flash could easily break again. There used to be a section in the Flash wiki on the wrapped 32-bit plugin which someone else deleted, I seriously considered bringing it back just so people would have it as a backup method.)
