4.4.0: gsk repeat, repeat-negative-coords tests fail with ngl on mips family
While trying to herd GTK 4.4.0 into Debian so we can upgrade to GNOME 40, I'm trying to resolve test failures in gsk.
On mipsel and mips64el, using swrast_dri.so
(I think that means llvmpipe), I'm seeing failures for the repeat
and repeat-negative-coords
tests with the ngl
renderer. Instead of being a checkerboard pattern of squares of flat colour, the top left pixel in each 2x2 block is darker than the other three.
The old gl
renderer removed in 4.5.x does not exhibit this particular test failure (I hope that gives someone a hint for where to look).
