Mac M1 bad visual connection between provinces

[Veu4on]

It's quite uncomfortable to play when the lines between provinces look like fancy transparent rectangles with thin colored edges.
Problem occurs regardless of installed mods or graphics settings. Tried to enable/disable: shadows, borders, pow2 textures, hires terrain and other settings - no result.
Various display modes (borderless/fullscreen/windowed) also did not help.
When I experimented with different map modes, I found that the problem only occurs in provinces that are colored (not grey). Only terrain map mode works perfectly.

I think it is a problem with eu4's opengl renderer in combination with some opengl implementations(e.g. I had it on my linux desktop with an nvidia card, but not on my old linux laptop with an intel integrated graphics and neither on my new laptop with an amd integrated graphics) . There have been a few bugreports about this and similar issues on Linux and macOS over the years, but I think the developers have kind of given up on the opengl renderer.

As a workaround, you could try out some map modes. They might have accidentally or intentionally fixed the problem.

On linux systems with an x86-64 CPU it is also an option to use the windows version of eu4 with its directx9 renderer with the help of proton, but I don't know if that's a viable option on arm macs.

There are apps like Parallels and VMware Fusion to run Windows under MacOS. Apple have Bootcamp as a dual-boot option, but I'm not sure it works on Apple Silicon Macs.

And of course there are options like Nvidia GeForce Now.
