Style issues with QTree

[hannesdelbeke]

I have a style issue with QtWidgets.QTreeWidget and QtWidgets.QTreeWidgetItem
when i hover over the item, it looks good (red H)
but when i don't hover over it it's white.

tested with other stylesheets, it happens with most others including default qt dark mode fusion
so likely something wrong with this widget i am using instead of the stylesheet.
Oddly 1 stylesheet does display it correctly, but 3 others don't and also have the white issue.

here i compare a brand new tree, with the tree that has the issue.
as you see the new tree with dummy data has no problems.
