fatal crash with godot

Start with the reported backtrace entries in scene/gui/rich_text_label.cpp:996 and core/cowdata.h:156, then reproduce the crash in Simula using Godot 3.4.beta.custom_build and monado-main. Compare the Xwayland and IPC errors with the crash context. Done means identifying whether the failure is in Simula or Godot and documenting a minimal reproducible setup or confirmed resolution.

the following error resulted in a return to desktop and crash of Simula. excuse the bad formatting but here is the dump:

Should I take this over to Godot? This is also with monado-main (latest upstream) and I had to do some less than ethical IPC configuration to get it to talk with Simula. it mentions an xwayland ipc pipe throw as well as some open-range bovine tipping nonsense so I wanted to check here first. Thanks
