I'm still seeing this problem using QScintilla in the version 3.5.1 
release of Scintilla. I tried to set the maximum to allow for the new 
annotations by calling verticalScrollBar()->setMaximum(newMaximum) but 
this seems to cause other bad behavior when using the scroll bar to 
scroll up one line at a time (the view jumps a couple lines or gets 
stuck for a few clicks). Is there a fix that's missing from this version 
of Scintilla?
