Does this bug still happen with any frequency with kde 6.5.5 ?

https://bugs.kde.org/show_bug.cgi?id=506892 [email protected] changed: What|Removed |Added CC||[email protected] --- Comment #28 from [email protected] --- I'm not sure this is a new problem unfortunately. I've encountered similar issues in the past (not entirely sure when I first encountered them anymore, but it was _well_ before Plasma 6.4, might have even been Plasma 5). In fact, I've had this exact issue again just ~a week ago and I'm still on Plasma 6.3.6 (Debian testing). This recent episode was apparently triggered by installing a large batch of plasma / Qt lib updates. The interface laggyness/hang happened pretty consistently after that. There has since been another large batch of plasma / Qt package updates in the last few days and I haven't been able to reproduce it since then (although I haven't used it that much since and now have another issue where plasmashell just crashes on login, so there's that). -- You are receiving this mail because: You are watching all bug changes.

I've just read up on your bug report. Surprised that it takes way longer for you. I wonder if "heavy system usage" accelerates this (I usually use Firefox heavily, like opening and closing hundreds of tabs and such). As for your offer, I don't really know what I can ask from you, because I don't know what causes this exactly. What I DO know that this has started happening on 6.4. I wonder if a change between 6.3 and 6.4 is causing this. -- You are receiving this mail because: You are watching all bug changes.

I am afraid I don't have any immediate ideas. So far it seems dbus is responsive and all threads on the process are also idle when this happens. Maybe something is stuck on a systemd level. But then krunner would also be effected... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=506892 --- Comment #17 from [email protected] --- You know what's weird? In other cases the apps work just fine. Like, say I downloaded a file, if I tell Firefox to open its folder, then Dolphin opens up instantly. Or if I launch Dolphin from KRunner, it opens up instantly too. But if I try to launch Dolphin from the menu/panel, it takes a long time and throws out that error, though it works fine afterwards. And everything works fine again if I force restart plasmashell. -- You are receiving this mail because: You are watching all bug changes.
