GLES2 RENDERER: Error Initializing Shaders

[iamkarlson]

Please fill out the following:

• Swayfx Version:

  • 0.2

• sway -v

  • 1.8.1

• Debug Log: https://pastebin.com/WZYSZiLq Sway running script: https://pastebin.com/zE8D55dR

• Description: Sway works fine with wlroot-nvidia package. However, SwayFX can't create a renderer.

For me with an NVIDIA gpu as well, I get those wlroots errors with normal sway as well, and it starts up fine, so it could be unrelated. Though i can only seem to get swayfx to do anything if i start it inside another wayland session (for me, hyprland). If i start it on a tty, it stops logging anything after it says "Starting sway version x.x-x" so i'm assuming on tty it just straight up doesn't work for some reason. While normal sway works started from a tty for me

I'm pretty sure that we don't support proprietary Nvidia drivers. What's your stance on this Will?

I dunno if you guys are gonna look into this further, but I poked around and found out that on my device that the error occurs on the tex fragment shaders. It seems to probably be all of them, but I only tested by letting the first errored shader go through and the next one also errored. (the ones created with link_tex_program)

found it, the shader was failing with the error 0(60) : error C7502: OpenGL does not allow type suffix 'f' on constant literals in versions below 120, so i removed the 'f' suffixes i found and it compiled and ran (i hope that didn't break anything, i assume it didn't?). haven't tested under tty yet tho so maybe that's still broken edit: yup, also works on tty now.

Thanks a ton for this investigation!

Thank you very much! I will check if it works
