I'm running ubuntu, and I have these packages installed:
And my graphic card is an intel x4500hd:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Normally (I misured it using the benchmark plugin) I have a framerate of more or less 100fps.
After enabling the blur plugin (in all its configurations, but I prefer the gaussian blur because it looks better) the framerate drops to 17fps.
I have to add that everything works (the blur plugin does not cause artifacts, and it actually blurs something, for instance the notify-osd popup, but not the metacity titlebar when it's transparent)
How can I help?
seems similar to bug#21579, but this one says no artefact.
Exactly. I don't know, they might be duplicates, and the artifact may only be present with the reporter's video card, which is a different model
I finally reproduced it on my system. It's triggering a CopyTexSubImage SW fallback.
OK, now I can't reproduce it again with:
- start compiz
- run ccsm
- check "blur windows"
- click "blur windows"
- check "focus blur"
- select "gaussian blur"
- drag windows around on top of other blurred windows.
Are you still having this problem with Mesa master? Can you provide details on how to reproduce if so?
I'm running on mesa master and also drm master, with also intel xorg git master.
I will now test if this bug is still present on my video card
Actually what causes the problem is gnome-terminal.
Normally I can drag windows over firefox at 55 fps (exactly the same as without the blur plugin), but try to open a terminal.
Even without moving it, the frame rate drops to 15fps.
Now minimize it, and you ave back your 60fps.
What's wring with gnome-terminal??
I have configured it with a solid white background color
Reproduced the problem again, then fixed it:
