[BUG] crashes before drawing starts with a certain configuration

Read the README.md and search for similar issues before posting a bug report!

Any bug that can be solved by just reading the prerequisites section of the README will likely be ignored.

Describe the bug

[A clear and concise description of what the bug is.]

Program crashes as soon as it starts.
Use the specific configuration (below).
Reproduces for me every run, not in other people's setups, I added extra info...
I also tried to debug it a little and it looks like a threading issue, because when create a breakpoint on the exact line (below) and stepping into slowly it will pass that line and die in a different spot. Doing the same there will progress some a bit more but the first place of this crash is in src/linux/btop_collect.cpp:1924:41 I have all so added here the compilation log and extra data.

feel free to ask me for anything.

[Steps to reproduce the behavior:]

run btop with a specific configuration (default config does not trigger the crash).

Screenshots

[If applicable, add screenshots to help explain your problem.]

This is the output with asan enabled. The program crashes before it started to draw anything:

so, with nvidia I was able to press 5 to get a gpu view as well. I since switched to AMD and not sure if limitation on btop's side or something else, but I don't have that view. now the bug will not reproduce so I assume we can focus on an issue when btop draws gpu
