Version: unspecified (using KDE 4.5.1) OS: Linux Since 4.5, I cannot activate effects reliably. In the window behavior/behaviour configuration panel, if I click "Activate effects", it sometimes does nothing, sometimes switch effects on, sometimes popups a message about Xorg not supporting (sorry I can't remember exactly. I think it's new to 4.5.2). Basically, it's unreliable. I hit enable and apply a couple of times until the effects are activated and a popup is asking me if I want to keep this setting. Clicking "Deactivate/Activate effects" button does not re-active them, I need to check the box and then apply. The activate button seems to always deactivate the effects. If I logout and login back in, effects are deactivated: the setting is not remembered. It is as if kwin had trouble detecting if the effects should be supported or not and fails most often then not. No special settings for specific effects: the default list of effects is used, which includes blur. Blue works on the machine (when effects are finally correctly activated) Effects are working since KDE 4, problems came up with 4.5 Reproducible: Always Steps to Reproduce: -Disable effects or log out/log in back -Check box "Activate effects" Actual Results: Effects are not activated, sometimes without even message. Many tries are necessary, until next logout. Expected Results: Effects are activated.
Forgot to say it happens on the two computers I use: -Dell Latitude D830 laptop: ArchLinux x86_64, kernel 2.6.35.7, Xorg 1.9, xf86-video-intel 2.12 (GMA965) -Asus EeePC 1000 netbook: ArchLinux x86, kernel 2.6.35.7, Xorg 1.9, xf86-video-intel 2.12 (GMA945)
likely related to bug #241402 (4.5 "fixed" the checks but causes issues since mesa didn't like multiple GL contexts (if one was on a non-window drawable) ) a) disable the blur effect (just to be sure ;-) b) what mesa version do you use? can you try >= 7.9rc2
a) I've disabled the blur effect. It seems the (de)activation of effects (using ctrl+shift+F12) is reliable. I'll see in the following minutes if it really disappeared. b) mesa 7.8.2-3. I will try mesa 7.9 soon. I'll check bug #241402 soon.

I'm seeing this too, using mesa-7.9 (final), though I'd since checked "disable functionality checks", so I'll try to re-confirm again later today.
SVN commit 1195271 by graesslin: Deactivate OpenGL compositing self-check. The self-checks have been broken for quite some time on several free drivers. It's probably better to have them disabled.
