OK, there is one use case that is simple to fix: writing in section. At 
TocBackend Level, only the current TocItem is updated, not the full 
list. We can do the same by means of a new signal that will trigger an 
update of only the current ToModel item. This way, the TocModel won't be 
reset and the tree will not collpase unexpectedly. I can do that later 
today or tomorrow.

I just committed something that should reduce the flashing due to the 
tree collapsing and then expanding. Not sure this has any effect on your 
platform.
