I tested the SDL3 "GetPrimaryDisplay" function and it doesn't appear to be any more reliable than our existing Vulkan method. The reality is that Wayland simply doesn't have the concept of a primary display and Factorio trying to specify a display to use is never going to work well on it.

I may ...

There are several blockers:

* SDL3 needs an official release (apparently on the 15th).
* Nintendo Switch port of SDL3 needs to be updated.
* We need to perform the upgrade and do thorough testing of all systems.

So it will be a while.


Hello, thanks for your input.
FYI SDL3 is now released ...
