Description

Falmeshot never worked good for me, it always made the screenshot selection small at the top left hand corner.

Now, after some time starting my laptop again and doing a full pacman and yay update (pacman -Syyu & yay -Syyu) i noticed, that it don't work at all.

Flameshot always give me "unable to capture screenshot" notification which is not really detailed so i ran it from terminal and got the actual errors:

When running without sudo:

flameshot: error: Unable to capture screen
flameshot: error: Unable to capture screen
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()

With sudo:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
kf.notifications: env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP
flameshot: error: Unable to connect via DBus

Steps to reproduce

1. run flameshot normally on Arch Linux, Wayland & KDE
2. receive error notification "unable to capture screenshot"
3. run flameshot from terminal to see a more detailed output
4. see the errors i posted above

Screenshots or screen recordings

No response

it always made the screenshot selection small at the top left hand corner.

You most probably have fractional scaling. That is another issue.

Update, when i run sudo flameshot gui it open sucessfully

You should NEVER run Flameshot as sudo.

neofetch is not useful for us. as we have explained in the bug report form, use inxi --graphics --system --width=80

Flameshot is unable to capture screen on Arch Linux, KDE, Wayland #3052

Please tell me how this is different from #2974 and #2880 ?

Ugh, I just arrived here from a fresh Arch Linux install and that's an old, unresolved issue?

worked fine until a couple days ago, no idea what changed.
