GLMakie segfaults using Threads.@spawn

I had some GLMakie visualization code that ran inside a @spawn block. It used translate! and rotate! calls on text, arrow and mesh plots without fail. When I tried to change a Label's text I immediately got segfaults. Replacing @spawn with @async fixed the issue. Note that I only get a segfault when I try to change the value of text[]. Accessing it (e.g. to print) works without any issue. The segfault was happening consistently, i.e. in every single execution, without any loops, other tasks, any sort of race condition etc. I managed to find a similar issue in a discourse post: https://discourse.julialang.org/t/unexpected-behavior-when-using-threads-spawn/103497

Here's a MWE:

  using Base.Threads: @spawn
  using GLMakie

  function init()
      GLMakie.activate!()
      fig = Figure(; size=(600, 600))
      GLMakie.Screen(fig.scene) # works fine without
      fig[1, 1] = textgrid = GridLayout()
      txt = Label(textgrid[1, 1]; text="Hello")
      return txt
  end

  function segfault(txt)
      println(txt.text[]) # works fine
      txt.text[] = "Goodbye" # crashes
      return nothing
  end

  txt = init()
  segfault(txt) # works fine
  @async segfault(txt) # works fine
  @spawn segfault(txt) # crashes

[x] are you running newest version (version from docs) ?

(@v1.10) pkg> st GLMakie
Status `~/.julia/environments/v1.10/Project.toml`
[e9467ef8] GLMakie v0.10.0

[ ] can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie) No. While both the versions of GLMakie and Makie are identical on the environment where I get the segfaults and on the clean environment, and they are the most recent versions too, I can't repro on a clean environment. I've pasted the output of st -m below.

[x] What platform + GPU are you on?

I don't know of how much help this is, since the behavior isn't reproducible in a temp env. I can try adding the other packages back until I get a segfault, if that helps. Let me know what I can do.
