SUMMARY
On both Wayland and X11, Dolphin's menu appears to suffer from the old 'korners' issue, where corners are black and not transparent. Submenus do not have this issue. Right clicking to open context menus in other places do not have this issue either.

STEPS TO REPRODUCE
1. Open menu

OBSERVED RESULT
Blank corners.

EXPECTED RESULT
Transparent corners.

Cannot reproduce at 200% scale on Wayland. Does the same thing happen for Gwenview's similar hamburger menu?

Indeed. Gwenview reports a version number 21.12.3 (same as dolphin). Perhaps it's been fixed since? Considering that other context menus, and even submenus of the broken menu do not show this issue, perhaps the wrong/an outdated style is being used, given that there was work to fix black corners not long ago IIRC.

Comment 4 Nate Graham 2022-04-04 21:46:59 UTC

It's a parenting issue in KHamburgerMenu itself IIRC. I seem to recall that it got fixed recently in Frameworks 5.93. Please feel free to re-open this bug report if you upgrade to 5.93 and find that it's not yet fixed for you.

Yes, https://invent.kde.org/frameworks/kconfigwidgets/-/commit/babd8078cc92b3f46dbab0286d7629ada1c2d10f should have fixed it.
