Could not launch OBS on Wayland and GNOME, Slack dies on screen sharing, Flameshot can't shot

HI! There is the fresh Tumbleweed on GNOME with Wayland and I have multiple issues with screen recording and screen sharing. Some apps can’t even start without some “play around” (for example, OBS Studio), and others die on screen sharing (Slack installed with opi). I believe that’s the multiple symptoms of one problem.

OBS:

# Then normal start

Slack:
Starting and working almost nicely until I try to share my screen. Then it throws this.

fish: Job 1, 'slack' terminated by signal SIGSEGV (Address boundary error)

Flameshot, if running from the menu, just doesn’t do any screenshots at all, and shows the message in the notification panel “Flameshot Error - Unable to capture the screen” only after I click exit.
But it does the screenshot if I run it from the terminal, what a heck.

@iromanyshyn Hi, see this page: https://flameshot.org/docs/guide/wayland-help/

I use the GNOME built in screen recorder and the slack rpm (from slack), also I run X11 not wayland…
