Comment (by ioctl):

 The same problem even without "Device doesn't support atomic float adds,
 disabling dispatch parallelism" warning.

 Example:

 wget https://imagemagick.org/Usage/images/rose.png # Download one image
 from the Image magick manual

 ffmpeg -y  -init_hw_device vulkan=vul -i rose.png -vf
 format=yuv444p,hwupload,nlmeans_vulkan=s=2.5:r=75,hwdownload,format=yuv444p
 rose-vul.png

 Problem appears on little and big image, in 420 and 444 color spaces.
