--- Comment #1 from br_shadow <tef...@gmail.com> --- Somehow the problem seemed to have fixed itself. I was having massive lag (system froze) spikes every minute that lasted about 15 seconds and I saw a process baloo_file_extractor that took up a lot of CPU. I deactivated the indexing function in KDE and now the lag has gone. Maybe the issue with the empty windows was somehow related. Anyway I hope this will help anyone having the same problem -- You are receiving this mail because: You are watching all bug changes.
