Lightning running slowly

Post by ra-thunderbird »

I've been using Lightning calendar for years, in the last 10 days or so, it's become sluggish.

When a Reminder comes up and is dismissed, the empty dialog box sits on the screen for 15 or 20 seconds before disappearing. I used "find events" to edit the ics file down from about 500kb to 181kb, but it didn't help.

Any ideas about how to fix this thing?
Thanks

I'm using Thunderbird 102.4.2, o/s is Ubuntu 18.04.
