Description
QTabWidget's left, right and bottom borders are missing when autoFillBackground is set true on each tab (not on QTabWidget itself). Bug appeared in Qt 5.10 and continues through to 5.15.0 snapshot today.
Simple test project and screenshots attached. PLEASE look at the screenshots carefully.
My most recent testing is on macOS 10.15.3 with xcode 10 and xcode 11.
