Moving the camera into a scene, turning on Ground Fog, waiting for the fog to form, then pressing Map 8K to take a snap locks up FlowScape. Requiring Alt F4 to close and return to the desktop.
FlowScape goes through the action of saving the image, but saves a solid grey image.
This is repeatable with the 8K Map and F8 and only after moving the camera into the scene.
Ansel takes 9K + snaps and the 2K and 4K work as expected.
Edit:
I do not believe it is a memory problem. I can enlarge the landscape, populate it with dozens of trees, rocks and birds. Move it left, right and pan it. The Map 8K works.
Only after I move the camera into the scene does the Map 8K crash FlowScape.
