[IMPORTANT] GLFW error and wrong (0,0) position about raylib-go

[gen2brain]

Well, the error is normal as Wayland doesn't support setting the window position. With the latest GLFW update binary now supports both X11 and Wayland and it will detect what to use in runtime (based on XDG_SESSION_TYPE).

What is not normal is that the coordinates are off, what compositor you are using? I tested a few examples and all works for me with labwc. Can you try in the X11 session just to confirm? Anyway, there is nothing that will happen here or that I can do to fix that. I can probably just return the wayland build tag, or maybe x11 tag to be something like compatibility mode, i.e. to force X11 on Wayland like before.

I use gnome. I just tried x11 and it seems to work (I changed the coordinates to (0,0) just to be sure):

As it worked in the older version, I think that forcing X11 would be the best solution.

[gen2brain]

The x11 build tag is added in c3665eb.

If you can, please also test with go build -tags sdl, as SDL will also detect and use Wayland I think. You can also force SDL_VIDEODRIVER to x11 or wayland there. I wonder if your issue is related to GNOME fractional scaling in some way and perhaps GLFW doesn't handle it properly.

I pulled the newest version with go get -v -u github.com/gen2brain/raylib-go/raylib
and the issue is still there (weirdly). With the sdl build tag, everything is as expected:

Without sdl it looks like this again:

go.mod is

module demo

go 1.22.0

require (
	github.com/ebitengine/purego v0.6.1 // indirect
	github.com/gen2brain/raylib-go/raylib v0.0.0-20240227114648-c3665eb9abf8 // indirect
	golang.org/x/sys v0.17.0 // indirect
)

did you change anything else since that version v0.0.0-20240125111008-83d871a38f28 ?

[gen2brain]

Check the output, when you see GLFW Wayland errors it is using Wayland. When you build with x11 tag, you should not see that anymore.

[gen2brain]

Also, if you already checked SDL, try to force wayland then force x11, to make sure it is not using the compatibility layer there. I mean, force with SDL_VIDEODRIVER=wayland.

[ax4w]

with x11 build tag, its working. Both sdl2 wayland and x11 seem to work aswell

[gen2brain]

Yes, you must use the x11 tag if you want the old behavior, the old one was to use X11.

[ax4w]

Alright, then it seems to be a problem with glfw and wayland i assume?

[gen2brain]

Yes, to be precise, with GLFW, Wayland, and GNOME/mutter, I guess it would work in KDE/Kwin, and I did a test in labwc where works.

I see, good to know. Then the issue is resolved :D you can close it now
