Just went one by one through my collection of patches to see if there are any broken ones with the latest 22.5 preview. Every third to fourth patch gamma silently crashed which does not happen with the latest stable or 21.4 previews.
I assume it is a Skia thing, because it is only happening with patches that reference Skia and have a Renderer in the patch. So to reproduce, just create that patch and open and close it a few times successively. Also one time I’ve got this error message.
