Problem with white background and masking in Print composer #51569

Closed oskarlin closed 3 weeks ago

oskarlin commented 1 year ago

What is the bug or the crash?

When making maps using symbol layer type Mask, for some reason, areas of the map that does not have any polygons covering then the white background turns gray in the Print composer.

A not so great workaround: If I create a huge polygon covering the whole map and style it white, then the background in the Print composer will be white.

First image: map project without any Mask layers. See the center where there are green dots. Second image: map project with one layer that has Mask layers. See the center where there are green dots.
