Native Wayland support

[pixelomer]

Running Shijima-Qt in XWayland to allow window repositioning is not ideal. A better alternative would be providing a separate backend for Wayland that uses the wlr-layer-shell protocol. wl_shimeji does this and it appears to work quite well with shimeji.

[claymorwan]

Would that mean we won't have the app in the taskbar ? From what I've tried, wl_shimeji don't have it so it'd be nice if it'd the same for Shijimia

[os-guy]

Also, there's some bugs with the Compositors / Window Managers such as Hyprland.
The Shimeji frame is updating but not deleting the old frame.
Also, the Shimeji background is just dark.

Adding these lines to hyprland.conf seems to fix most of the issues related to Hyprland:

windowrulev2 = noblur,class:Shijima-Qt
windowrulev2 = noborder,class:Shijima-Qt
windowrulev2 = noshadow,class:Shijima-Qt
windowrulev2 = float,class:Shijima-Qt
windowrulev2 = nodim,class:Shijima-Qt
windowrulev2 = pin,class:Shijima-Qt

windowrulev2 = nodim,class:Shijima-Qt
windowrulev2 = pin,class:Shijima-Qt

This is for the Flatpak Package right?
And nope, it didn't fixed.
Also, wl_shimeji works fine on Hyprland (Without this black screen and rendering issue)

[pixelomer]

My understanding is that wl_shimeji creates an overlay above all other windows using a Wayland-specific protocol. Unlike Shijima-Qt, it doesn't create a separate window for each shimeji, so the shimeji aren't really managed by the desktop environment and wl_shimeji has more control over them.

The main goal of this issue is to use the same protocol wl_shimeji uses to make Shijima-Qt work better with Wayland compositors, while remaining compatible with X11 and other operating systems.

idk what distro u on, but if it's arch or arch based u can try with the aur package maybe it'll work

[pixelomer]

I use Fedora 41, both the binary and the Flatpak version work for me with this configuration

I both tried AUR package and Flatpak package.

I managed to get a native Wayland backend working with Shijima-Qt! It relies on the wlr layer shell protocol and so far it seems to work great on Hyprland and KDE Plasma. I'll finish it up and try to get a new version out as soon as possible.

[pixelomer]

Preliminary native Wayland support through wlr-layer-shell is up on feature/wayland-layer-shell. It's very incomplete at the moment, but please give it a try if you're interested.

The program will still launch in X11/XWayland but when you choose Settings > Backend > Wayland, the app will create a Wayland overlay for showing shimeji. From my testing it seems to work as expected on Hyprland, KDE Plasma and other wlroots-based compositors. It doesn't work on GNOME since GNOME doesn't support wlr-layer-shell.

Erm about that, I cloned, switch to theb ranch and pulled then tried to compile but I get an error saying that wayland-protocols/wlr-layer-shell.h is missing :c

Try running make protocols-autogen before compiling, I may have forgotten to do that as a part of the build process.

Erm, error again apparently

$ make protocols-autogen

Could not open output file: No such file or directory
make: *** [Makefile:92: protocols-autogen] Error 1

[pixelomer]

...great, I messed up the last commit

• Remove the line after protocols-autogen: in the Makefile (line 91 starting with mkdir)
• Run mkdir wayland-protocols
• Run make protocols-autogen

If it fails after that, you're probably missing a dependency. Try installing the development packages for wayland-protocols, wayland-client and wayland-cursor. You can run make protocols-autogen again afterwards. Once that succeeds you should be able to build normally.

[claymorwan]

It compiled ! Tho like yea as u said there's a bunch of weird stuff going one when activating the Wayland backend

[pixelomer]

The Wayland backend should be mostly working:

• Dragging/throwing should work as expected
• It might be hard/impossible to catch shimeji while they are falling (?)
• Transparent areas are not passthrough. It is possible to make them passthrough but the current method I have for doing so causes really high CPU usage in the compositor
• Right click menus do appear but they may not be interactive/usable depending on your compositor (?)
• The overlay has a white tint, this is intentional and used for testing, I'll remove it once the changes are finalized

[claymorwan]

Well for what I've noticed when activating the Wayland backend (on KDE) :

• Shijemejis have a weird outline
• Hovering shemjis disable the cursor theme for some reason
• If 2 shimejis interact with each others (for example these in the screenshot can hug), the app just crashes

here's the log btw if that can help (with the crash at end happening when the interact together)

Btw I see another backend called Qt Widgets, what is it ?

[pixelomer]

• I haven't noticed any outlines in my testing, I'll see if I can reproduce that
• The cursor is provided by wayland-cursor, I don't know how cursor themes work so I can't comment on that
• I haven't tested interactions but I don't think that should cause any problems (?) I'll look into it

[claymorwan]

For the cursors I just tried with multiple different ones but all of them just return to the black one, not really sure what to do qwq
