Greeter is blurry in HiDPI

[elementaryBot]

we have the correct UI scale, but all the things in the clutter actor are blurry. It looks like the UI scale is set some time after the greeter is initialized. Either we need to wait until gsd starts up and sets the UI scale, or we need to somehow refresh the actor after the UI scale changes

Someone created this: https://bugs.launchpad.net/elementaryos/+bug/1700688
It has a screenshot of the avatar glitch.

It looks as though this is an upstream issue in clutter-gtk. Even after the avatar widget has now been re-worked to respond to DPI changes, it seems as though clutter does not propagate that event to the GTK widgets in the stage properly.

There's information in bugzilla here:
https://bugzilla.gnome.org/show_bug.cgi?id=758937

There's a patch to fix the issue that landed in clutter-gtk 1.8.2 which ties in with what @tintou was saying about it being fixed in Artful.

FWIW - I backported the clutter-gtk and gtk3 patches from the bug reports to xenial (clutter 1.6.6 and gtk 3.18) and set up a PPA for myself. The widgets are still blurry. Tried some steps like rebuilding granite and greeter (from master) and ensuring the gtk3 packages were built and uploaded before the clutter packages in my PPA, also rebooting etc. but to no avail.

Probably some other unknown/unresolved bugs in clutter and/or gtk causing the blurred result with hidpi in xenial. So, unless there are any further ideas, we might have to wait for Loki+1 to look forward to further hidpi improvements. Should I just close my PR #51 then?

My PPA is here if anyone cares: https://launchpad.net/~vishalrao/+archive/ubuntu/elementaryos

The bluetooth (and only this one) icon is still blurry in new greeter at 4K and scaling x2.
Once I switch off the BT it becomes crisp and stays like that till next reboot when, again, per default it is blurry.

@DanyGee can you please report that against the Bluetooth indicator?

[DanyGee]

Sure!
