--- Comment #3 from Thomas Lübking <thomas.luebk...@gmail.com> --- You can ignore that error - it means KWin wanted to adjust a window that's already gone. This causes a server error, but is harmless, and the alternative is to grab the server all the time (as window managers exclusively deal with windows with unknown lifetime) - what means your desktop would kinda lag ;-) The "bug" here is the excessive default debug output. -- You are receiving this mail because: You are watching all bug changes.
