ngl renderer fails to render custom widget (node file attached)
reposting from IRC:
i was drawing the rectangle with a negative height (starting from some offset y)
this worked in other renderers
for ngl i had to do this properly with no negative height
not sure if gtk bug or just user error that happens to work in other renderers
To reproduce just try to draw a color node with a rectangle that starts at a y offset and draws in the negative direction (i.e., use negative height).
This is how it should look (works on GL, vulkan, cairo renderers):
This is the node file:
This is how it currently looks (green lines missing on ngl renderer as of 4.13.7):
