Maybe look into PipeWire, Reaper in jack mode works fine connected to PipeWire for me, without any of the problems you mentioned.

It is quite possible that your desktop audio already uses PipeWire depending on your distribution, you would need to look at latency settings if you want live playback.

CLOG is very enjoyable to work with. I only have nice things to tell about developer experience and quality of documentation.

Next, they are going to ban importation of crowbars, because these tools can theoretically be used to pry open some car doors.

I am not a lawyer this is not legal advice.

Search for copyright assignment agreements, there are a few good template documents. I’d request a signed document instead of simply stating it in the PR. In all cases I would recommend verifying the document and process by a lawyer before you start using it.

Also, I would consider not requiring copyright assignment if at all possible for the project in question.

A lot of fun so far ! Thanks for making this

If I understand your reply correctly (the output of free would be clearer), having 80% of RAM used as cache would indicate that it is used for caching files such as map and chunk data. This is normal in Linux, and the game would lag more without this feature. The link I shared explains it better than I can.

If you feel this is still not the case, you can share info such as free output, list of open files, etc, while the issue occurs.

There might be an actual issue in your case, but this feels to me like https://www.linuxatemyram.com/

I’m expecting mapping will write a lot of map data to files in your world folder which might explain the apparent high ram usage. Try looking at disk usage while the issue occur maybe ?

Open source Not […] allow […] commercial applications

For some definitions of open source, this is contradictory (FOSS). Some non FOSS licenses do limit commercial use while making the source available, this could be a possibility for you.

But, I’d instead recommend that you check if a copyleft license such as the GPL provide enough protections for your use case.
