I have a 4K display running on 1440p and I noticed the Ubuntu's logo and name are not sharp in the about page (see attached picture)

Can this change be reverted?

Version-Release number of selected component (if applicable):
gnome-control-center-42~rc-1.fc36.x86_64

How reproducible:
A+++

Steps to Reproduce:
1. Install latest Fedora Workstation 36 testing image
2. Go to Settings > About
3. Behold blurry Fedora logo

Actual results:
Blurry Fedora logo

Expected results:
Clean and sharp Fedora logo

It looks fine to me on gnome-control-center-42.0-4.fc36.x86_64

Can you try updating to the latest and check again? The other possibility is that it may be related to the resolution (hidpi?). I see that your image is 2553x1390, which is not a common desktop resolution.

Proposed as a Freeze Exception for 36-final by Fedora user carlg using the blocker tracking app because:

no blurry for me at RC1.4

Fedora-Workstation-Live-x86_64-36-1.4.iso seems good to me here

resizing the settings window

[sgallagh (sgallagh-redhat-bugs)]

Okay, I see it now. If you expand the settings window vertically, the logo enlarges in physical size but not in image resolution.

I requested that revert because I tested the change on F35 and found it caused gnome-control-center to display the logo at a huge size. It was obviously broken.

I didn't test F36 or rawhide, though. These are different because they use GTK 4 instead of GTK 3, with different underlying widgets to display the image. Perhaps it's totally fine. Just needs to be tested.

It's probably only blurry on hidpi, which is likely why I didn't notice.

Ah... I see.

The one missing thing here - an upstream issue: https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/1815

[geraldo.simiao.kutz (geraldo.simiao.kutz-redhat-bugs)]

Then why it doesn't happen when I tested rc 1.5? https://bugzilla.redhat.com/attachment.cgi?id=1877196
Resolution related?

Yes, looks to me like you don't have enough vertical resolution to pull it down far enough to notice the transition.

If the image is small, works fine, but image can't scale lossless. I think it has a PNG, but it should be an SVG.

Status changed to 'Confirmed' because the bug affects multiple users.

[bachfreak15 (bachfreak15-redhat-bugs)]

Any news on that issue? Just updated to F37 and this behaviour still exists.

[Sebastien Bacher (seb128)]

Is that still an issue in the current version?
