gnash using 100% CPU

I wonder if anyone can reproduce this. What version of Gnash?

gnash version 0.7.2-1build1 as in Feisty repository.

I can reproduce this bug, running Ubuntu 7.04 on a Powerbook 5,6. I had this problem with Ubuntu 6.10, too.

me too with 0.7.2. Also now i used prevu to update to the cvs snapshot available in gutsy repository, and I still have the same problem of 100% cpu. On iBook (Powerbook6,7)

mee too in gutsy, with version 0.8~cvs20070611.1016-1ubuntu2
not only the mozilla plugin, but also the gnash executable. This is the debug log

is this a graphic card problem?

what does

 # glxinfo | grep direct

give you on console?

direct rendering: Yes

are videos rendered using some acceleration??
if so radeon cards have *very poor* quality, using the open source driver

I have a mobility 9700

Maybe you can try if the non free drivers improve your performance?

non-free fglrx is not available in gutsy yet

Same problem on Gutsy Gibbon running nvidia proprietary drivers with Geforce Go 7400, all recent gnash packages including the latest one.

I am unable to reproduce this with nvidia-glx-new package installed for my nvidia 5200 and using gnash.

my comment https://bugs.launchpad.net/ubuntu/+source/gnash/+bug/91910/comments/11 is on 3 pcs non of them are macs.

Imight suspect that the hi CPU usage is caused by the radeon
opensource driver (I have an r300 card)
Can anyone try with fglrx?

same slowness with fglrx, just tested now

I've experienced this today on AMD 5600+ X2 machine with nVidia propretory drivers on 8600GT graphics with Fiesty 64 bit. 84% CPU on gnash process ( all available ) makes everything run very very slow.

Gtk-gnash has very high processor usage, often steadily at 100% , on my computer (Athlon 3000+ on A8N-VM-CSM with nvidia driver) as well.

Hardy version of gnash still have this problem.
Putting back to confirmed, since it is also available on intel graphics.

I doubt this is related to the video driver in use. I am suffering this problem frequently on Hardy (updated to almost-8.04.1) and on an Intel i915GMS (using xserver-xorg-video-intel).

Note that gtk-gnash keeps eating away CPU in the background, even if Firefox has been quit long ago. "killall gtk-gnash" cures the problem.

This bug should be upstream to https://savannah.gnu.org/bugs/?26718

Is this still an issue with Ubuntu 12.04? Gnash now uses a different renderer.

This bug was due to slow OpenGL renderer, current gnash no longer use it.
