Poor AnimatedImage performance

    XMLWordPrintable

Details

    Description

       

      I compared the performance of Flutter, Qt, and React Native in rendering.
      Everything was in order until I decided to use AnimatedImage in my tests.
      All that the app was doing was displaying X gifs in a grid.
      For X=18 the Qt app was already using a lot of memory. It was almost 1GB.
      For X=200 it quickly maximized the available memory and the app died.

      Underlying QMovie probably causes that.

      Competitive frameworks didn't have those problems.

      I've tested with Qt 6.3 and 5.15.2.
      Attached is the code source of the app and a screenshot from the profiler (for X=18).
