Since last 17.10 update yesterday, thunderbird looks terrible, needs always mouse-over to display any menue contense and text while writing keeps disappearing, can temporarily be found back by zooming in or out, only to disappear in clusters again... completely unusable. Thanks for fixing...

I have used 17.10 since alpha from daily builds, updating every other day or so, never had any mayor issue, only the 'new' Thunderbird - which i depend upon - seems to have serious issues. Thanks for fixing ;-)
