Run Chromium/Electron under Wayland natively (conf files apply to Arch Linux, BTW ^_^)

README.md

These Flags may only apply to Arch Linux Offical packed packages.

Flags disabled for now

1. ~/.config/chromium-flags.conf

# --wayland-text-input-version=3 # not sure, if not using kwin or hyprland, should be added
# --disable-features=UseSkiaRenderer # not sure
# --enable-gpu-rasterization # may not needed
# --ozone-platform-hint=auto # fallback option
# --disable-features=WaylandFractionalScaleV1 # may not needed
# --gtk-version=4 # may not work with fcitx5
# --use-gl=egl # may break AMD GPU

2. ~/.config/code-flags.conf

# --enable-features=WaylandWindowDecorations # may needed under to gnome to show title bar
# --enable-webrtc-pipewire-capturer # when needed
# --enable-features=TouchpadOverscrollHistoryNavigation # not sure
# --ozone-platform-hint=wayland # fallback
# --disable-features=WaylandFractionalScaleV1 # may not needed
# --gtk-version=4 # may not work with fcitx5
# --ignore-gpu-blocklist # not sure

BTW, MS VSCode on Arch Linux may not read these flags under .config directory. (Only work with Arch Linux Official packages (Code - OSS) and visual-studio-code-bin(AUR)).

If choosing use MS VSCode (Proprietary Microsoft-branded), may need to add flags to the .desktop file and which can be created at ~/.local/share/applications/code.desktop.

The window decoration should be fixed with "window.titleBarStyle": "custom".

3. ~/.config/electron-flags.conf

# --ozone-platform-hint=auto # fallback

4. Jetbrains's IDEs (Java Swing) could use -Dawt.toolkit.name=WLToolkit to enable wayland support.
5. for xwayland work in hyprland: hyperland setting as follow

# change monitor to high resolution, the last argument is the scale factor
monitor = , highres, auto, 2

# unscale XWayland
xwayland {
  force_zero_scaling = true
}

# toolkit-specific scale
env = GDK_SCALE,2
env = XCURSOR_SIZE,32

may need to do something in ~/.Xresources and install xorg-xrdb if u want to do factional scaling

Xft.dpi: 144
Xft.autohint: 0
Xft.lcdfilter:  lcddefault
Xft.hintstyle:  hintfull
Xft.hinting: 1
Xft.antialias: 1
Xft.rgba: rgb

then run xrdb -query -all or run xrdb ~/.Xresources.
