Openbox menus slow down after changing the brightness

Hi, I'm using an Acer Aspire Timeline 4810 laptop, and I've noticed that after I change the brightness the menus slow down considerably. Anyone know why this is happening? This specific model of laptop also has issues with opengl and changing the brightness, so I guess that it's possible that it's related to that...

Flash also seems to slow down in fullscreen after the brightness change.

Re: Openbox menus slow down after changing the brightness

do you have cairo compositing on. I know that that slows down the menus a bit also are you using the openbox or xfce versions of #!.

I is natural, at least for what I've noticed. for flash to be rather bad with full-screen on linux. especially if you have an older laptop. (I don't know how old yours is)

I wish you luck!

Re: Openbox menus slow down after changing the brightness

I'm currently using the openbox version, and compositing doesn't seem to have any effect (I tested it with cairo-compmgr on and off). Fullscreen flash normally works fine (it's not a very old computer), but after I change the brightness it's slows WAAAAY down.

Re: Openbox menus slow down after changing the brightness

It doesn't appear to... It's holding pretty steady around 15-20%, which is where it was before I changed the brightness.
