Bug Description


Shell text and some icons have sharp edges during zoom. Screenshot attached.

[Test Case]

1. Settings > Universal Access > Zoom = ON
2. Click on the time/calendar and look closely at the font edges.
Expect: the edges should be smooth when zoomed.

[Regression Potential]

Low potential effect on other parts of Gnome Shell. The code being changed is only used in shell popup menus at the moment.

[Other Info]

This is not an important bug at all. Its fix is just a happy consequence of fixing the more important bug 1767648, so that's why it is getting SRU'd - for bug 1767648.

Hmm, archive isn't showing that version yet but it was only 10 minutes ago so I will give the Janitor the benefit of the doubt for a while.
