Chromium blurry with "output * scale 2"

[maletor]

When comparing sway vs i3 with Xft.dpi 200, chromium is not doing something correct with the scaling and it appears blurry.

Chromium has force-device-scaling but it shouldn't be necessary as it can read from the DPI of your screen to set the scale correctly. Is this a bug in Chromium or sway or wlc? Are you able to reproduce?

Xwayland does not support scaling.

[maletor]

Thanks for the quick response. I understand you are working on this longer term with wlroots. Appreciate it.

@maletor i think you misunderstood: Scaling will ever only work correctly with wayland applications. Chromium still uses X and there for Xwayland unter sway and will not scale correctly until it switches to wayland.

[maletor]

@torpak but what about Chromium's internal force-device-scale-factor flag? That would work with XWayland correctly?

[torpak]

@maletor I have no idea, since i don't use chromium. But as i understand it that would be the same for all environments using xwayland for legacy applications. So maybe you should ask chromiums developers?

Just to provide on update on this for anyone that finds this issue. At some point in the last 2 months this was fixed. With absolutely no changes from me chrome auto-scaling now looks crisp and correct.
