Not working on Ubuntu 20.04 with Wayland

Doesn't work on Ubuntu 20.04 because they bumped their GNOME version to 36.
Are you sure your problem was caused by upgrading to version 3.36? I'm on Fedora 32, and this extension works with Gnome 3.36. However, it works with the xorg version of Gnome, but not with the wayland version. The wayland version is the default session under Fedora 32, maybe this is also the case for Ubuntu 20.04?
Ubuntu 20.04 here: ShellTile works just fine for me as long as I'm running Xorg.
@Masterkraft0r, could you run echo $XDG_SESSION_TYPE in a terminal and paste the result here? If it says Wayland then this is the same issue as #99.
Works for me on 20.04 on Xorg.
Yup, with Xorg works fine but with Wayland up to the next reboot.
The issue with Wayland is that when doing a meta_window.move_resize_frame and immediately after a meta_window.get_frame_rect, the dimensions do not match, as in Xorg. Instead, on Wayland, the position and size at the beginning on the event handling is returned. This is necessary because some applications enforce a minimum weight like nautilus or a height that has to to be a multiple of a fixed line height like in gnome-terminal.
Is this a bug or a feature of Wayland/Mutter? Is there a way to know when the position and size have changed? A callback maybe?
The doubts were cleared here https://gitlab.gnome.org/GNOME/mutter/-/issues/1533. Wayland has async event handling so the move_resize_frame isn't immediately reflected after checking the minimum size required by the application. This means ShellTile needs almost a rewrite to address this behavior and work on both the display servers. I'm working on it.
Hi Emanuele,
For your information, Ubuntu 21.04, the new stable release since 22 Apr, run with Wayland by default, not X.Org. And the Gnome Shell version is 3.38.4.
G.
A rewritten version, completely async, is available in the wayland-compatibility branch. It works flawlessly on X and it's almost stable on Wayland but there are still some cases where the sizes are not adjusted correctly. You can test it and tell me if you find on Wayland some minimal reproducible bugs.
Hi Manuele,
I have downloaded the wayland-compatibility branch extension, build and install it. It work's well now for me (Ubuntu 21.04, Wayland).
Thanks a lot,
Giles

Can you explain how you installed this? I am executing build.sh and running the command gnome-extensions install ShellTile@emasab.it.zip. It seems like it works fine, but when I do gnome-extensions list, ShellTile does not show up as an installed extension.
Edit: I found instructions on #67. However, this does not work for me due to #123.
I have installed on wayland as well... works nicely but there is a large amount of empty space between windows where you can see the desktop background
this isn't the case with the built in gnome split screen where windows border each other
edit: my bad, first time user here, I wasn't aware this was a feature
so far the wayland branch has been working great
May I suggest to add some kind of disclaimer "Not working on wayland yet" (with Link to this ticket) in the description of the extension page (https://extensions.gnome.org/extension/657/shelltile/) so that user quickly find hints and understand (I guess for Ubuntu current LTS fresh installs, wayland has become the standard, so there will be more and more questions coming to you).
As additional measure (if it is not too much work and in the master branch only until you merge the candidate), you might integrate a visible hint "Not working yet on wayland" in the extension configuration popup visible only if wayland is detected as display manager (if it is some kind of information available from the extension perspective)
I have recently been running from the extensions page on 20.04 wayland https://extensions.gnome.org/extension/657/shelltile/ and it works great, for the first time you install it. after rebooting it stops working and snapping does nothing. I have to uninstall and re-install for it to do anything
Last commit to the default branch was Feb 5, 2021.
