KCalc on KWin 5.23.5

SUMMARY

See the attached comparison. The only system changes between the two screenshots were upgrading KWaylandServer and KWin from 5.23.5 to 5.24.0. (KWin 5.23.5 won't build against KWaylandServer 5.24.0.)

The left and right window borders appear to have their gradients painted left-to-right rather than top-to-bottom.

STEPS TO REPRODUCE
1. Install KWin 5.24.0.
2. Choose Oxygen as your window decoration style.

OBSERVED RESULT
Left and right window borders have gradients painted left-to-right with brighter edge on the left.

EXPECTED RESULT
Left and right window borders have gradients painted top-to-bottom with brighter edge at the top.
