I tested only with WinCairo MiniBrowser. I can't reproduce this bug with Mac MiniBrowser. Cairo port bug? Preferences?

Not reproducible with GTK MiniBrowser. WinCairo specific bug?

Comment 3 2022-09-29 20:52:32 PDT
Downgrading cairo 1.17.6 to 1.17.4 fixed the problem. It seems like cairo 1.17.6 regression.

If I build cairo-1.17.6.tar.bz2 with meson, it has no problem. It seems like a CMake script problem. https://github.com/WebKitForWindows/WebKitRequirements/blob/main/ports/cairo/patches/0001-Add-CMake-build.patch
