    Description

      I opened KDE Bug#461723 for this issue. There I was asked to bring this here.

      Today I had Gwenview crashing with a similar backtrace, see below.

       

      QTBUG-93067 seems kind of similar.

      This seems to happen more often, if I disable my second screen. I configured it to the left of my main screen.

      If I understand the function copy_unswapped right, the variable yy is kind of a resolution in y-direction - but my screens don't get somewhere near that value of 8256.

      Unfortunately I don't have a way to reproduce it. I observed this one times with a dolphin process, twice a konsole and today one gwenview process.
