Version: (using KDE 4.1.3) Installed from: Ubuntu Packages Sorry about the mouthful of a title :-). Here it is in steps: 1. Open systemsettings. 2. Click on any icon. 3. Change any setting, but don't click Apply. 4. Press the Escape key. The "unsaved changes" dialog will appear as expected. However, the system settings window behind it is now all grey - you can't see anything at all.
Here using: Qt: 4.4.3 + qt-copy-patches-889120 KDE: 4.2.60 (KDE 4.2.60 (KDE 4.3 >= 20090106)) kdelibs svn rev. 908156 / kdebase svn rev. 908156 on ArchLinux x86_64 - Kernel 2.6.27.10 I can confirm this bug
*** Bug 180200 has been marked as a duplicate of this bug. ***
Created attachment 30632 [details] Proposed patch Not the best solution but the best I could find. Bypassing some KDialog/QDialog keyPress event to catch the ESC keyPress. This may be a KDialog bug
