See the "How to get a core file out of the X server?" section of the Xenocara README [1]. You can then load Xorg and the core file into gdb/lldb. I think ports egdb may do better in some cases? Others who are more knowledgeable can weigh in on that. Potential workarounds: use the "vesa" X driver instead of "vmware"? I think VBox supports that but I don't remember. Another option is efifb/wsfb, which of course requires configuring the VM for UEFI mode and reinstalling. Both probably have lower performance though. -Andrew [1] https://github.com/openbsd/xenocara
