Running Thunderbird 38.2.0 with Lightning 4.0.2 in Windows 8.1. A few Thunderbird versions ago, had to disable Lightning because the UI started flashing repeatedly. With Lightning disabled, everything works fine. Tried disabling, removing and reinstalling Lightning, and the problem came back. Any ideas as to how to fix it?

do you use a non default theme? What calendars do you have installed in Lightning?

Hi, thanks for answering. At the moment I'm using Microbird, and I get the problem there, but also with Littlebird, Nautipolis and even the Default theme - same problem again. I've also disabled all other extensions, but that didn't help. Re: installed calendars, I used to have the provider for Google Calendar installed, but that's all, as far as I know. I disabled that long ago and still get the problem.

Grateful for any further advice
