## Notes on wlroots-0.19
There are some regression warnings worth noting for the switch to wlroots 0.19:
- The DRM backend now destroys/recreates outputs on VT switch and in some cases
on suspend/resume too. The reason for this change was that (i) the KMS state
is undefined when a VT is switched away; and (ii) the previous outputs had
issues with restoration, particularly when the output configuration had
changed whilst switched away. This change causes two issues for users:
- Some layer-shell clients do not re-appear on output re-connection, or may
appear on a different output. Whilst this has always been the case, it will
now also happen in said situations. We recommend layer-shell clients to
handle the new-output and surface-destroy signals to achieve desired
behaviours.
- Some Gtk clients issue critical warnings as they assume that at least one
output is always available. This will be fixed in `Gtk-3.24.50`. It is
believed to be a harmless warning, but it can be avoided by running labwc
with the environment variable `LABWC_FALLBACK_OUTPUT=NOOP-fallback` to
temporarily create a fallback-output when the last physical display
disconnects. [#2914] [#2939] [wlroots-4878] [gtk-8792]
- Menu item can no longer be activated in any Gtk applications with a single
press-drag-release mouse action. For context: This is due to ambiguity in the
specifications and contrary implementations. For example, Gtk applications are
broken under KWin in this regard, while vice versa Qt clients are broken under
other compositors like Weston, Mutter and labwc. It has been decided not to
block the release due to this regression as it is an eco-system wide issue
that has existed for a long time. [#2787]
- It is strongly recommended to use at least wlroots 0.19.1 [#2943]
