|
||||
- Various Wayland protocols
|
||||
- XWayland support as provided by wlroots (can be enabled in `config.mk`)
|
||||
- Zero flickering - Wayland users naturally expect that "every frame is perfect"
|
||||
- Layer shell popups (used by Waybar)
|
||||
- Damage tracking provided by scenegraph API
|
||||
|
||||
Features under consideration (possibly as patches) are:
|
||||
|
||||
- Protocols made trivial by wlroots
|
||||
- Implement the input-inhibitor protocol to support screen lockers
|
||||
- Implement the idle-inhibit protocol which lets applications such as mpv disable idle monitoring
|
||||
- Layer shell popups (used by Waybar)
|
||||
- Basic yes/no damage tracking to avoid needless redraws
|
||||
- More in-depth damage region tracking ([which may improve power usage](https://mozillagfx.wordpress.com/2019/10/22/dramatically-reduced-power-usage-in-firefox-70-on-macos-with-core-animation/))
|
||||
- Implement the input-inhibitor protocol to support screen lockers (see https://github.com/djpohly/dwl/pull/132)
|
||||
- Implement the idle-inhibit protocol which lets applications such as mpv disable idle monitoring (see https://github.com/djpohly/dwl/pull/133)
|
||||
- Implement the text-input and input-method protocols to support IME once ibus implements input-method v2 (see https://github.com/ibus/ibus/pull/2256 and https://github.com/djpohly/dwl/pull/12)
