Texture buffer on macOs has been a pain to try and fix it, and afair the performance with it turned off should be roughly similar, specially on M series chips. I suggest you turn it off

Go to preferences -> Display, and turn off "Use texture Buffer"

Fix artifacts appearing on the canvas when cropping the image

The image resize signal should be syncronous to make sure
there is no race condition for the data fetching from the image.
