Steam apps can't select proper resolution about labwc HOT 15 OPEN

When wlr-randr shows a scale factor of 1, does the game then provide the correct resolution?

from labwc.

Yes it does. So how can I achieve both?

from labwc.

You ask the author of the game for proper scaling support, or you manually switch to unit scale before you start the game. wdisplays is a helpful tool. I don't think this is a labwc problem.

Its not a single game, its all games with steam.

Then that sounds like a problem with Steam.

from labwc.

Just fyi. the problem doesn't exist on KDE Wayland session.

from labwc.

KDE is not a wlroots based compositor and they might very well have added workarounds for steam.

Have you tried any other wlroots based compositor, sway, hyprland, wayfire, etc?

from labwc.

It's come to my attention that Steam is an X11 application, and the problem you're seeing is common to all X11 applications with Xwayland.

from labwc.

Yes exactly and it makes labwc unuseable as desktop WM if you have a HiDPI screen. If I understand the settings correctly you are describing in the manual, the wlr-randr scale should not affect XWayland applications. For that purpose you have the xprop and GDK Scale options? Here is how KDE is doing it: https://wiki.archlinux.org/title/HiDPI#Xwayland_2

Also the scaling for apps like signal-desktop from flatpak looks much more crisp on KDE with scaling like this:

After reading some more this might actually not be fixable by labwc:

If it's unusable, use something else. This is not a labwc issue.

from labwc.

While technically correct, this is kind of a wlroots / xwayland and thus labwc issue.

If I understand the settings correctly you are describing in the manual, the wlr-randr scale should not affect XWayland applications.

It will affect xwayland applications by wlroots scaling the xwayland buffers up by the scale factor. Thus they look blurry, there needs to be some solution in the longer term.

from labwc.

For games, using gamescope should be a viable workaround as it has built-in scaling options independent from labwc

Sadly I haven't found a solution with gamescope which works for me. With capital width and height the game still doesn't offer the correct resolution in game or doesn't even start properly (the later is probably a problem of the game).

from labwc.

Might this solve this issue in the future? https://www.phoronix.com/news/XWayland-Rootful-HiDPI-Merged

Also is there any work on the integration of this or how does one check if rootful xwayland is supported by labwc?

from labwc.

rootful xwayland is supported by labwc (and should be the same for any other wayland compositor as its basically just a regular wayland client from what I remember):

Xwayland -decorate -noreset :55
DISPLAY=:55 dbus-run-session openbox-session

Rather than starting openbox-session you could obviously start whatever you like.
Note that this will not show the windows within that X11 session in A-Tab, render labwc decorations or similar. It might be fine to run that fullscreen for a single game though, never tested that approach and also can't say anything about the performance.
