Description Marcus Harrison 2010-07-07 21:55:28 UTC 
Version:           0.2 (using Devel) 
OS:                Linux

When desktop effects are on with Direct Rendering disabled, switching the widget theme makes the entire screen besides the mouse unresponsive. Applications (and KWin) still respond to mouse and keyboard input, but nothing on-screen changes, making it unusable until KWin or X is restarted.

Reproducible: Always




OS: Linux (i686) release 2.6.32-24-generic
Compiler: cc

If this can be reproduced only with compositing effects, it is a KWin bug.
Comment 2 Thomas Lübking 2010-07-08 16:28:45 UTC 
- GPU/driver?

- KDE version (4.4 or 4.5 beta / trunk)

- does SHIFT+ALT+F12 (suspend compositing) /after/ the freeze "fix" it?

- by "widget theme" do you mean 
a) the plasma theme (desktop "widgets") or 
b) the Qt style (buttons, scrollbars, etc. - QWidgets)

- which kwin decoration do you use? (oxygen, aurorae, ...)
Comment 3 Marcus Harrison 2010-07-30 23:13:19 UTC 
GPU: Intel Atom (945GME) Integrated Graphics with Mesa driver
KDE 4.4.92 (RC2).
Yes, temporarily disabling using Shift+Alt+F12 unfreezes ("fixes") the screen.
Oxygen widget theme: theme for applications, not for the desktop (so "b", QWidgets).
Using the Oxygen windeco.

Sorry it took me so long to reply - I didn't catch the message in my inbox.

this is most likely related to bug #241402 and LIBGL_ALWAYS_INDIRECT, please try to add
export LIBGL_ALWAYS_INDIRECT=1
to ~/.xprofile, login and out and see whether the issue remains

(sorry for the delay myself...)

I am very sure that this is the same bug. Please reopen if it's not the same one. Thanks
