@goatwildernesscollective @dos It works for old apps too, provided that they aren't too old to support Wayland. If they rely on Xwayland, scale-to-fit does not work IIRC.
@linmob @goatwildernesscollective Yeah, implementing it for X11, although not exactly impossible, would be much more involved. The easiest way would be to have a separate XWayland servers for scaled apps, as then X11's global coordinate space wouldn't get in the way.
@goatwildernesscollective @linmob You can enable scale-to-fit feature in phoc to scale oversized windows down. It's not enabled by default so app developers don't end up relying on it, but users can always turn it on as a workaround for misbehaving apps.
