[Bug]: Conky doesn't show a window on Wayland

[kleshas]

What happened?

Running sway, updated arch (new install). AMD 6750XT

Not sure when it started but recently my previously-working config only shows a blank window. I saw a link on google saying this can be caused by an external IP lookup happening too often, but removing that from my config didn't help.

When out_to_x=true, out_to_wayland=false I get a blank conky window. When out_to_x=false, out_to_wayland=true I don't get a window at all (though there is a conky running in htop).

Actually, it seems that the window DOES eventually populate, but after a few mins, and it seems to not be doing any further updates (I have a time entry in the config, it hasn't changed for 5 mins).

With out_to_wayland=true there is no change using own_window_type override, desktop or normal.
Running from command line:
conky -c ~/.conkyrc
conky: drawing to single buffer
conky: FOUND: console
conky: FOUND: ncurses
conky: FOUND: file
conky: FOUND: x11
conky: FOUND: wayland

and nothing after.

conky-cairo (1.21.2) has the error: "unknown setting out_to_wayland, and Unable to find a usable display output when using out_to_wayland=true

looks like AirVPN was causing the blank screen. Mullvad VPN doesn't have this issue. I do still have the issue with out_to_wayland=true not working.

Having the same issue with out_to_wayland = true not displaying any window.

The issue started somewhere between versions 1.19.6 and 1.21.6. With the deb package in Ubuntu 24.04 (1.19.6), I can still see a window when using Wayland. With the 1.21.6 AppImage, the window is blank as described.

I'll download some other AppImage versions and see if I can find the exact version where this issue began.

Edit: The issue starts with version 1.21.0. The AppImage for 1.20.2 displays a window when using Wayland, and the 1.21.0 AppImage does not.

own_window_type does nothing on Wayland. In future, it should allow configuring window to require sizing/placement like X11 counterparts, for now it's always on the background layer of zwlr-layer-shell.

Closed issue confirms this bug on KDE besides Sway, so I'm merging them here as this one is older.

@abkein confirms this issue on Hyprland as well.

Running hyprctl reveals that window is mapped, focusable, and should be visible:

Window 5ef2019dbb90 -> ./src/conky:
	mapped: 1
	hidden: 0
	at: 2,28
	size: 956,1050
	workspace: 3 (3)
	floating: 0
	pseudo: 0
	monitor: 0
	class: kitty
	title: ./src/conky
	initialClass: kitty
	initialTitle: kitty
	pid: 687435
	xwayland: 0
	pinned: 0
	fullscreen: 0
	fullscreenClient: 0
	grouped: 0
	tags: 
	swallowing: 0
	focusHistoryID: 1

So this probably has something to do with how buffers are drawn/swapped.

Hi, i can confirm this also happens in labwc (wlroots based). It works if i use it via xwayland, but if wayland fallback is enabled and selected, there is no window.

This is what works at the moment for me:

    out_to_wayland = false,
    out_to_x=true,
