Unusable perspective live filter with embedded file

[Marekius]

AMD Ryzen 7 5800H
32 GB RAM (20 GB limit set in AP)
GeForce RTX 3060 laptop
Win 10

I'm trying to create a mockup, so I have a file with 6k px x 4k px size, where there is only a laptop image). When I place embedded affinity photo file (1920x1080, 1 image) and use perspective live filter on it - everything becomes unstable and unusable. Deleting the perspective filter does not change anything, once added it makes the whole app slow and barely responsive. I need to restart the app. While unresponsive and laggy, AP does not seem to use much of resources (would have expected CPU/GPU at aroud 100%).

Disabling OpenCL helped here.

Hey Marekius,

You are right, I've just reproduced this on a much smaller file with a 3080 and after a few adjustments it started to lag and become unresponsive and finally I started seeing really bad rendering tiles. I'll get this logged - thanks!
