Some particular animations are too slow in vulkan backend.

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.

WAYLAND_DISPLAY=wayland-1 QSG_RHI_BACKEND=vulkan QT_VULKAN_LIB=/Downloads/1.2.182.0/x86_64/lib/libvulkan.so.1 QT_QPA_PLATFORM=wayland ./animation
