Is 1.3 the problem?

[hanatos]

are you using a desktop environment? which one? did you set a content scale factor? wayland and macos have this !@#$% idea that the mouse events should be scaled by some extra factor that can be set by the desktop and may or may not have anything to do with screen dpi.

vk 1.3 is okay. vkdt just doesn't ask for the newest version to give old systems a chance.

[ax006ho]

I'm using Gnome with a saling factor of 200%. Setting this to 100% makes the mouse work correctly, but I can't read any description :-(.

Is there a remedy?

[hanatos]

hm. temporary workaround might be scaling factor 100% and fltgui/dpiscale:2 in .config/vkdt/config.rc. which version of glfw are you using? do you have multiple screens? the content scale factor should really be propagated through wayland->glfw->vkdt and be applied.

[hanatos]

oh one more question, on your desktop what is:

$ echo $XDG_SESSION_TYPE

?

and are you sure you run native wayland and not through xwayland? if you run vkdt -d all from console, what is the output?

[ax006ho]

the output from the two mentioned commands is attached. stdout.txt

[ax006ho]

the temporary workaround works, you can see the glfw version in the previous mail. The problem: I cannot work without scaling becase I'm using a 4K monitor and all other characters are too small for my old eyes.

I'm using a single screen.

[hanatos]

thanks for the output!

[gui] glfwGetVersionString() : 3.3.10 X11 GLX EGL OSMesa clock_gettime evdev shared
[gui] vk extension required by GLFW:
[gui]   VK_KHR_surface
[gui]   VK_KHR_xcb_surface

this says that glfw is using xorg not wayland. since you're on the older glfw 3.3 there may be two distinct packages on your system, one glfw and one glfw-wayland? not sure if fedora would provide newer glfw 3.4 that has both x11 and wayland support? this one would automatically use wayland in your case, and probably avoid all the scaling issues.

(i have to say i'm really annoyed how f^&ed up the scaling is in the whole wayland ecosystem. and how all compositors, all windowing libraries, and all client applications have to contain the same hacky workarounds querying a set of environment variables and s*&t to fix it up)

[ax006ho]

Sadly to say that there is only one glfw package on Fedora systems as the attached output says glfw.log

glfw 3.4 is announced for Fedora 42 :-(

[hanatos]

okay, in the mean time try this:

$ export XDG_SESSION_TYPE=x11
$ vkdt

because the envvar is straight up lying when it says wayland and then glfw runs xwayland.

[ax006ho]

That works perfectly, thank you very much!

[hanatos]

awesome. closing this as "completed" while we wait for wayland+friends downstream to mature and make it to packages in distros.
