Bug

Description

Qt applications have some redraw issues primarily concerning popups and tooltips. Parts of previously displayed popups or tooltips will stay behind and sometimes flicker on and off when the UI updates itself (e.g. blinking input cursor in KWrite, updating progress bar in Cantata).

Note that the redraw artifacts only show up in OBS recordings when "Region" is selected in the share picker, not when "Window" is used.

So far I only observed this in Qt applications, namely KWrite and Cantata (a Qt mpd client) - they are running as native Wayland applications. Haven't seen this outside of Qt yet.

Ghost borders in KWrite were fixed in #5113 but the issue of entire parts of the word suggestion popups staying on screen remains as shown in the video attached below.

How to reproduce

  1. Open KWrite.
  2. Write or paste a bunch of text, e.g. generated Lorem Ipsum.
  3. Start writing more text while attempting to repeat words already in the document so that the word suggestion popup starts appearing.
  4. Keep typing like that for a while, the issue should show itself pretty quickly.

For Cantata, see the attached video below. It's simply hovering UI widgets to show tooltips that triggers it after a while.

Notice the right edge of the play button leaving behind redraw artifacts for a short while.

can't repro. Try fiddling with the config, maybe bisect?
