Rendering is blurry again (hidpi) - has workaround #304

Open f1yn opened 1 year ago

f1yn commented 1 year ago

I'm not sure how to test this as I rarely use Flatpak, but it would seem that Chromium has become blurry again on hidpi, even when the Ozone detect platform is set to auto or wayland.

For context, I think something has potentially negated a patch that was made a few months ago - but I can't see any recent changes upstream, but I don't have enough information to l

Current version (from flatpak list):

I am going to see if I can rollback versions and see if it was the latest system update I did that killed text rendering.

Update:

Reverting to cfe3c544f465cc2f4c3c69bf6bdda705961c41e3b6f10ab7eaa9b0d43e171f94 seems to restore text rendering - so the change is isolated to the Chromium upstream and not something else (I thought maybe it was Mutter).

Oof I should've made note of this, recent Chromium releases ship Wayland fractional scaling support that's blurry on current Mutter versions. You can work around it by adding this to ~/.var/app/org.chromium.Chromium/config/chromium-flags.conf:

features-=WaylandFractionalScaleV1

or manually passing --disable-features=WaylandFractionalScaleV1.
