Wayland

While trying out Ubuntu 23.04 via Ubuntu Sway Remix 23.04, I've noticed a lot of issues with blurry programs. After doing some research, I've found that this is due to applications using the X11 protocols to access the display via Xwayland instead of using the native Wayland protocols. I didn't have this issue running Ubuntu Sway Remix 22.04, so I'm very curious what has changed.

I'm starting to document what I'm learning hear and adding links.

atlauncher on Arch / Garuda Linux

In order for atlauncher to run properly in Sway or SwayFX on Wayland, you need to tweak the Exec line by adding env _JAVA_AWT_WM_NONREPARENTING=1 as shown below. This is the launcher file located at /usr/share/applications/atlauncher.desktop

[Desktop Entry]
Name=ATLauncher
GenericName=ATLauncher
Comment=A launcher for Minecraft which integrates multiple different modpacks to allow you to down
load and install modpacks easily and quickly.
Exec=env _JAVA_AWT_WM_NONREPARENTING=1 atlauncher
Icon=atlauncher
Terminal=false
Type=Application
Categories=Game;
Keywords=game;Minecraft;

Flatpak

VS Code

Adding "--enable-features=UseOzonePlatform --ozone-platform=wayland" to the code launcher fixes the issue. I updated all of the /usr/share/applications/code*.desktop files appropriately.
