Impeller inconsistency when using ImageShader in CustomPaint #165205
Description
Steps to reproduce
I have a visual effect where I show an animated 3D cube in Flutter, projected to 2D and with images rendered as its sides using ImageShader in a CustomPaint. This used to work, but starting in a recent Flutter version (maybe 3.29.0?) it does not work in Impeller anymore.
Expected results
I would expect the result between Impeller and --no-enable-impeller to be consistent.
Actual results
Impeller has a new behavior different from --no-enable-impeller.
