Lightning category list shown "black on black"

Post by yxlan »

Ubuntu MATE, TB 45.2.0, Lightning 4.7.2, everything standard

I'm running out of new ideas, when editing calender events or task and trying to select categories for an item the list of categories is shown in black on a black background ... which makes it hard to read ](*,)

Hover and selecting an item changes the visibility of the list item. Problem does not occur on another system running Xubuntu.

Any ideas how to fix? I assume some *.css needs change or additional definitions, but I can't find the right place.

HELP PLEASE!
