Using the blender build to render the standard cube with cycles in one viewport leads to a crash. Since I can’t upload attachements I’ll provide you the content of “blender.crash.txt”:

Rendering the standard cube with cycles in blender 4.1.0 Beta, branch: blender-v4.1-release, commit date: 2024-02-20 18:18, hash: a3ffb51da6c5
doesn’t crash. This blender version does crash if e.g I have two viewports in one blender instance, both rendering in cycles at the same time (both counting the samples), no problem if one viewport has finished its rendering.
