hidpi: Allow individual scaling for applications #225

Open kaueraal opened 7 years ago

kaueraal commented 7 years ago

Some applications, especially X11 applications, support hidpi, but currently do not support waylands internal scaling protocol for signaling this to wlm/sway. It would be nice to be able to set individual scaling or disable it altogether for certain windows on wlms side to get sharp scaled rendering nevertheless. This would allow a smoother transition to sway/wlm/wayland for hidpi-users, especially as this affects both chromium and firefox.

See also SirCmpwn/sway#1047.

I said in my issue (and you failed to communicate here) that per-application DPI is not possible for Xwayland views. I asked you to open an issue asking if we could set the DPI for Xwayland globally at startup.

kaueraal commented 7 years ago

Where did you say that? At least on the issue I opened you didn't comment. Still, that limitation would make this feature relatively useless :-/

A global option to set the xwayland buffer_scale would be very helpful. Users willing to configure the various X scaling options (Xresource etc) could then have a blur-free Wayland experience with xwayland apps by setting the xwayland buffer scale equal to the output scale of their largest display. Seems like this could be a small change in wlc? Junior job?

Probably.
