Description

7 months ago
User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0

Steps to reproduce:

1. Run any new linux distro with GNOME
2. Set 200% scaling in display settings
3. use Arc GTK theme
4. disable firefox titlebar in customize

More info here: https://github.com/NicoHood/arc-theme/issues/138

note: Ubuntu Ambiance has this issue too


Actual results:

Firefox is not rendering the image from background-image property of the window controls with 200% scaling.


Expected results:

The window controls should be rendered at high resolution and not be blurry

Still the case on nightly 65.0a1
Can you please try Wayland builds? Run GDK_BACKEND=wayland ./firefox on Wayland enabled system. X11 has trouble to support 200% scale when running on semi-HiDPI systems.

So sorry I didn't see this earlier.

I am not sure what you mean by waylan builds, but nightly has it right? I updated today.

Test: latest firefox-trunk, logged in to a gnome wayland session. Ran with command GDK_BACKEND=wayland firefox-trunk

Still got the blurry buttons still, and loads of weird window resizing issues. I could send a screenshot if it is useful but I assume it is not as nothing has changed since the last time.

Also what do you mean by semi-HiDpi?

Tell me to stop if should stop saying this over and over, but it's still been a problem on latest nightlies.

I tried wayland launching again, they were still blurry.

A dupe of Bug 1419467?

When your monitor doesn't have high density DPI (I think it's DPI > 196 or so) you don't get HiDPI by default in X11 and you can't set it by the scale factor in X11. The HiDPI/Scale factor works in Wayland only in that case.

Ah it seems you are right about that! Should this be closed?

Ah :/

Let's do the work at Bug 1319838.
