--- Comment #5 from Rafał Mużyło galtgendo@o2.pl --- Created attachment 60342 --> https://bugs.winehq.org/attachment.cgi?id=60342 a tweak fixing the problem
To clarify shorthand: the problem with item position is still valid, the part with the tooltip *might* be fixed ("might" cause the tooltip no longer shows up at all...:sigh:).
Nevertheless, attached nearly trivial patch *for the most part* seems to fix the problem, though it raises a question of where does the desync comes from. I'm not calling it a complete fix, cause while it fixed the second app, in the Wolf Editor, while after a single resize things work properly, before that the treeview is blank (most likely one of the values used by TREEVIEW_ComputeItemRect isn't initialized early enough).
