I'm using meld and i have several konsole windows open. Typical workflow is to alt-tab quickly (without showing the icons-preview of the open windows) between meld and konsole. Quite often, the return from konsole to meld does not work - instead, some other (random?) window gets activated. Of course, if the icons-preview is shown (pressing alt-tab and keeping alt pressed for a longer time) hits the proper target, it affects only the 'quick'-switch without preview
i might have found the problem (but not a solution to it) i run audacious in the background. Each time, a song changes the Alt-Tab goes to audacious (and not a random window) So song is playing, alt-tab between browser and konsole works fine song ends, changes to the next song alt-tab goes to audacious first.... This did not happen in X11 Any ideas??
Interesting. It definitely seems like Audacious is causing the issue, but it remains to be seen if it's 100% an app bug, or if there's anything KWin is doing wrong in response to it.
