Height Brush severly broken on 2.22.2-SNAPSHOT

[IR0NSIGHT]

when testing my plugin with this worldpainter:
<dependency> <groupId>org.pepsoft.worldpainter</groupId> <artifactId>WPGUI</artifactId> <!-- Update this to the version of WorldPainter you wish to test with: --> <version>2.22.2-SNAPSHOT</version> <scope>compile</scope> </dependency>
i noticed that rotated brushes are leaving very wierd artifacts.
tested with an empty Plugin that adds no operations or layers

reproduce:
run worldpainter at stated version with empty plugin (dont know how to run the desired snapshot without the plugin)
take any non-trivial brush (heightmap brush, not radius-calculated brush), f.e. default set -> perlin noise
rotate 45° degree (or any other that is not 0,90,180270)
apply height brush
