Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

When viewing certain pages in Firefox on windows with window borders of other
applications overlapping certain parts of letters (typically vertical sections
of "t" and "d" but possibly others) certain irregularities can be seen with
fonts, as seen in the area circled in red in the screenshots. If the affected
text is highlighted the affected area is fixed, and the text following the
aberration moves to the right, which can be observed in the second screenshot.
This appears to be related to repainting of fonts in the firefox window when
switching between applications, though I'm by no means an expert.

Reproducible: Sometimes
