An example that showcases the bug.
When using unit tests I sometimes see this behaviour on Ubuntu, I think it is related to #404

I'm willing to contribute a PR to fix this, but I will need some guidance

@suarezjulian Does this sound like the same issue as #368?

In any case, it would be great if you could investigate this and provide a fix. I didn't yet have time to look into this. My suggestion would be to make a smallest reproduction case possible, then convert that case into a unit test in this project, then try to figure out how to get the unit test to pass and isolate the underlying bug.

@mislav yeah that looks related or even the same issue as this one. I will try to create a smaller test case
