That's all I've seen too on linux. I attempted to produce a daily build for win64 using the thunderbird "try" server but my credentials had expired. So I've now done a local build on and for windows and am running that. So now maybe I can see something happening since I only saw the problem on windows. The version I'm running now is 100a1 as built from comm-central latest. I'll do some testing now on windows and see if the problem still occurs.
