(In reply to Dave Flanagan from comment #9) > Sadly this bug is back in 91.8 64bit. After about three days of normal Thunderbird use with no occurrence, the same symptoms are back where the current folder window blanks on a bug delete until you change folders and return. It is interesting that the update to the new version appeared to stop the behavior for a while. Seems like a persistent queue somewhere is overflowing! Once in a while, I find TB to completely "white screen" for me but I am certain it's because I am on an ancient laptop with ancient drivers (that cannot be updated). Something akin to a screen draw/re-draw issue. I often have to move my mouse around the TB "white screen" to make things visible again or invoke a restore down / restore up action to make things come back to normal. I don't know that's it's related but are you on old hardware or old GPU drivers as well?
