--- Comment #48 from Jaap Geurts <jaap.geu...@fontys.nl> --- I just had it happen to me again on 5.25. I also use a multi-monitor(usually 2 external monitors) and multi activities setup. I'm a laptop users and I connect to many different monitors during the day(I'm a hot desking user). For me it always happens upon switching to another desk with a different set of monitors. It seems that kde doesn't recognize the new monitor(s) or recognizes them too late or relabels the monitor. Then it thinks the new setup has no activity(containment) and decides to create a new activity(containment) for each monitor which makes me lose my old activities(containments). It won't switch back either since the new one is working fine and now the default. Only very occasionally does it revert back) -- You are receiving this mail because: You are watching all bug changes.
