    Description

      I verified qtwayland clients with vulkan rendering backend.

      But some particular animations are too slow on vulkan backend.

       

      I tried to run the below example on vulkan backend (only client side).

      According to my analysis, using SequentialAnimation and ParallelAnimation at the same time on vulkan backend is a problem. In other words, the animation is too slow.
