Red Hat Bugzilla – Bug 243089
Using gnash hangs system.
Last modified: 2007-11-30 17:12:06 EST
Description of problem:
I have used Firefox with gnash-plugin. On some sites with moving flash there are
horizontal squiz on screen like data written in wrong video memory place (I'm
not sure). It works several seconds then hangs. X can not be killed. In several
seconds NumLock stops to respond on pressing- system hags completely.
Version-Release number of selected component (if applicable):
Fedora 7 versions, no old ones- new installation. I don't know verisons on gnash
and gnash-plugin because I have to remove them immedietelly.
Firefox was updated since.
On some site with dynamic flash banners.
Steps to Reproduce:
1. Try to visit http://mail.ru. I have problems rigth there.
Viewport 0 0
This is not a bug of gnash only. Indeed gnash should never be able
to crash X. But it is likely that there is a also a bug in gnash
which triggers it to send malformed data to the mesa/X system.
You don't need to remove gnash, removing gnash-plugin is enough.
Going on http://mail.ru I cannot see where the .swf file (the flash
file is). Could it be possible for you to find it out? I'd like to
try to reproduce with the stand-alone gnash player.
I cannot reproduce a crash with the stand-alone gnash player
included in fedora, nor with the cvs gnash stand-alone player
Does the stand-alone gnash player crash X with this file for you?
But maybe it is another flash file?

.swf on which gnash hangs system
Baner saved from mail.ru
I can reproduce visiting http://mail.ru with gnash-plugin installed and with the
standalone gnash. swf from mail.ru is attached.
Same situation with file you have attached.

Maybe you could try to rebuild locally gnash to see if it
is the same bug than Bug 217020

I have rebuilt it using rpmbuild -ba, then install compiled standalone gnash.
Result: same horizontal lines on the screen.
I am not completely sure, but it seems to be a duplicate of
Maybe you could check the X backtrace to be sure.
