Description
Sorry for the long title...
I'm using the following expression to change the size of a simple marker according to the map scale:
CASE WHEN $scale < 750 THEN 0.42 ELSE 4 END
This works for a simple point layer. When using this with "point pattern fill" style for polygon it does not work. The simple marker does not change its size.

Similar strange things happen with SVG markers instead of Simple markers in point pattern fills. The size of the SVG markers are changing only by panning and not by zooming. My expression:
CASE
WHEN $scale < 750 THEN 5.6
WHEN $scale >= 750 AND $scale < 1250 THEN 4
WHEN $scale >= 1250 AND $scale < 3000 THEN 2.8
WHEN $scale >= 3000 THEN 2
END

Thanks for fixing this. The second issue (changing size of svg markers only by panning) still arises from time to time. Should I open a new ticket.
Can I debug the scale that the renderer is using?

Yes please open a new ticket and attach a test project.
