OBS screenshare fails

[colin-heffernan]

OS is NixOS Unstable, using Hyprland via the flake.

Any time I open OBS, the screen is black, and the same error is consistently printed to journalctl. What journalctl --user spits out:

Do you have qt6-wayland?

[colin-heffernan]

Would I have to install it separately? If so, then no.

[vaxerski]

it is a dep of the AUR pkg.

[vaxerski]

AH FUCK

I did an oopsie in one line while doing the Rev2 PR. Sec.

But yeah qt6-wayland still reqd.

[vaxerski]

verify plox

[colin-heffernan]

On it, will update ASAP.

[colin-heffernan]

The Hyprland flake still uses the old version ATM.

[vaxerski]

can't you compile manually? ugh, nix. @fufexan

[fufexan]

Updated, please check.

[colin-heffernan]

Sorry for the late-ish follow-up. I'm getting the same error.

[colin-heffernan]

Nevermind, I had to restart the compositor, all is seemingly resolved. Thanks, everyone!
