Texture size 2048 causes texture inpaint deadlocks

[jclarkk]

I was wondering if I should open an issue on this since it was hardcoded on 1024, but since you've raised it yourselves to 2048 as I have tested in the past I thought it should be more suitable now.

In some input imagery, the texture inpainting simply freezes. I've supplied here the input images that have caused it on my end but I'm sure there are more that could be problematic.

I should mention I've reproduced this on both RTX 4090 24GB and A100 40GB.
