Owner

Thank you for the report! Slipstream 1.4.0 Beta 6 is out (https://slipstreamviewer.org) and is a stability-only release aimed at exactly these crashes: several graphics buffers were being re-created in the middle of a frame (which Windows drivers often turn into a "lost device" / driver crash), plus a batch of fixes found with Vulkan validation tools. The newer rendering features that Beta 5 switched on are off again by default.

Could you please update to Beta 6 and let us know here whether the crash still happens? If it does, a new report from Help > Report Bug in Beta 6 (it attaches the log) would help a lot.
