MC LAUNCHER 2.1.7658 not starting under Wayland using Ubuntu 18.04 and Ubuntu 19.04.
The icon appears but the main windows / UI never appears. Previous launcher version worked fine.
The following appears when launched using the cli:
(minecraft-launcher:31037): Gtk-WARNING **: 13:06:22.363: Theme parsing error: gtk.css:3841:23: Junk at end of value for outline-offset
(minecraft-launcher:31037): Gdk-WARNING **: 13:06:22.447: ../../../../../gdk/x11/gdkwindow-x11.c:5611 drawable is not a native X11 window
Reinstalling doesn't work and i can't seem to revert to the previous version since i can't find any launcher archive containing these downloads. Changing the display server to xorg renders the Minecraft launcher to launch like it supposed to but using xorg as the main display server is a no go.
edit: running the following command starts the launcher under Wayland using x11: GDK_BACKEND=x11 minecraft-launcher

I'm having the same issue on Ubuntu 19.04. I have to log in to an x.org session for this to work. I would much rather use Wayland, the game runs better on Wayland.
Additionally, the newest version of the Linux Minecraft launcher will crash old versions (pre-1.14.4) versions of the game when trying to launch them. Running in terminal will say "SaveToBuffer failed".
@Linus: That first video is not posted by me and doesn't show the issue we are discussing over here. The issue we are facing is we can't run the minecraft launcher under Wayland cause you get nothing more than a icon.
edit: i've now added a video showing the problem (minecraftwaylandissue).
Same here. With ALT+TAB I see the icon but not the window.
Fedora 30 and 31. Oracle Java and OpenJDK.
{{SaveToBuffer failed}}

On Fedora 31 I have created ~/minecraft/minecraft-launcher/start-minecraft.sh to start Minecraft
#!/bin/bash
export GDK_BACKEND=x11

Same issue here, the mentioned workaround works.
