    Description

      Steps to reproduce:

      • open a document in QtCreator (e.g. 15KiB or more) so you can scroll
      • scroll somewhere in the middle, left-click in document text, so cursor is blinking there, too
      • right click -> context menu is opened
      • press esc -> so context menu is closed
      • scroll up or down
        -> here is the jump

      The bug-trigger is probably the context menu because this it can also be triggered by opening context menu anywhere else (on desktop or other application).

      This is happening probably for all Qt applications with scrollbar. I can also reproduce with kate, konsole and ark.

      This bug is here at least since version 5.4 (didn't test older versions) so it is not a regression.
