Chrome For Android Font Rendering Bug


The latest version of the Chrome Browser for Android has introduced a curious rendering bug.

When scrolling, I notice that the font hinting seems to break down. This makes the text very "juddery". It looks like the fonts shrink and grow and they scroll. This is very disorienting when reading.

In this example I've noticed that once I've stopped scrolled the page, the fonts are hinted differently.

I've enlarged the examples (without interpolation) so you can see them a bit more clearly.

To give you a good idea of what's happening, I've magnified the letter "e" (again, without interpolation). You can quite clearly see what happens to the font.

I can understand why the font hinting changes as the scrolling occurs - but why does it change even after scrolling has finished?

All screenshots taken on an N7100 running 4.1.2 with the latest version of Chrome for Android. The Galaxy Note II has a fairly standard resoltion of 1280×720, giving it 267 PPI - that shouldn't cause any problems.

This issue has been reported to the Chromium team.
