    • Bug
    • Resolution: Unresolved
    • P2: Important
    • None
    • 6.6

    • Linux/X11

    Description

      • Open examples/quickcontrols/texteditor/texteditorexample.
      • Change to edit mode.
      • Select all, copy, paste repeatedly, so that the amount of text grows exponentially.

      The texteditor becomes more and more sluggish and unusable. Scrolling is nice and snappy, but selecting text is laggy.

      P.S. tested on a Raspberry Pi 4, so the processor is a bit on the slow side.
