Wayland

Check for wayland supporting apps here.

Firefox

For good touchpad scrolling, set these in about:config.

mousewheel.min_line_scroll_amount = 150
mousewheel.default.delta_multiplier_x = 30
mousewheel.default.delta_multiplier_y = 30
mousewheel.default.delta_multiplier_z = 30

Chromium

Use wayland backend by creating the file ~/.config/chromium-flags.conf with the following content:

--enable-features=UseOzonePlatform
--ozone-platform=wayland

Wireshark

Wireshark on sway does not show the menu and the context menu (right click). A temporary fix is to run Wireshark with QT_QPA_PLATFORM=xcb set.

QT_QPA_PLATFORM=xcb wireshark

Electron

Tell Electron apps to use wayland backend. Create ~/.config/electron-flags.conf with the following content:

--enable-features=UseOzonePlatform
--ozone-platform=wayland
