• Qt WebEngine subpixel antialiasing regression?

    From Brendon Higgins@21:1/5 to All on Wed Jan 20 05:10:01 2021
    Hi all,

    I'm wondering if anyone else is experiencing this: Qt WebEngine text content
    is not getting subpixel antialiasing, even though subpixel antialiasing works correctly most other places (including other Qt/KDE widgets). For me I notice the problem particularly affects Falkon and KMail in the message pane: in those places, all text is antialiased greyscale and not subpixel RGB.

    This old QT bug report is related and shows what I mean: https://bugreports.qt.io/browse/QTBUG-62146
    In fact, the test case attached to that report also fails for me - I get
    output like "Qt5.8.0.PNG".

    It looks like that regression was once fixed and has now regressed again! Unless something's just weird on my install... I'm running Debian Testing with Qt 5.15.2 packages installed.

    Best,
    Brendon
