Description Dainius Masiliūnas 2011-07-18 15:32:52 UTC

Version:           2.4.1 (using KDE 4.6.0) 
OS:                Linux

Every time Amarok displays a notification, either using the OSD or KNotify, and the system is running a fullscreen program, the screen flickers for a while and the fullscreen program sometimes loses focus.

Reproducible: Always

Steps to Reproduce:
1. Enable Amarok's notification system, either OSD or KNotify.
2. Enter a fullscreen application, for example, a Flash video.
3. Change the track or wait for the current one to finish.

Actual Results:  
Depending on the fullscreen application, the screen might flicker in white or show graphics corruption for a short amount of time, sometimes followed by the fullscreen application losing focus. OSD makes this period of flickering or corruption longer than using KNotify. In the latter case, it happens only when the notification is about to disappear, never when it appears.

Expected Results:  
OSD and KNotify should be automatically disabled when a fullscreen program is being run.

Using openSUSE 11.4 with KWin compositing, graphics card ATI Radeon HD 4980 with Catalyst 11.5 drivers.

This is more likely a problem with the underlying graphical system, reassigning.

Oops, wrong element, sorry for the noise.

Comment 3 Martin Flöser 2011-07-19 16:47:43 UTC

disable unredirection of fullscreen windows in advanced compositing settings as a workaround. Will be the default in 4.7
