I have the same issue and it seems to be (somewhat) related to KDE Plasma as well, because it launches properly on Sway. Nvidia GPU (latest propriety drivers), runs properly on KDE with the parameter above. Thanks! userreport_hwdetect.txt

Yeah, of course ! That's what I want to do but, I think it would be better if it could help 0AD... I don't want to do a mod which will never help or becomes part of the main game !! I created this discussion to find out whether my ideas and project are good or too ambitious to start modding...  He will help me with my mod and, if he likes this experience, he might even join (like me) the project ! He's been a programmer for about 20 years I think (or more)

Having multiple markets of the same players on the same route should stay less efficient, lest it becomes exploitable. But the OP idea of having a route with multiple markets of different allies (max one market per ally) should be made a little bit more efficient (I don't think it would be hard to tweak the formula to make it so) as it's funnier, has nice strategic implications, and is immersive (that's how trader worked historically).

I've tested all cases I could think of but we can always give it a couple days to see if something broken is discovered. If not, I don't have a gitea account or repo set up, and I might be lazy to set one up (a bit of other reasons too that makes me not want to do it maybe...). I've made a version SnappingWalls.zip of the code that use function overwrites and comments cleanup to make it easier if someone want create a PR for main game.

Who is that person? How good are they at JavaScript?

If you wan’t to get started, you could make a mod. It’s pretty easy to do, and is a good way of learning how the coding and design is for 0ad, without slowing down game development with any errors or flaws that you accidentally have (and there will be many, believe me). In fact, several mods have actually been made a part of the game over the years, so if your mod is high-enough quality (or you make a pull request), your mod could be added as well. There is not much work for a beginner at coding, but more art and civs is always welcome. I recommend, if you want to join in the actual development, check for work here: https://gitea.wildfiregames.com/0ad/0ad/wiki/GettingStarted
