Description gregorystarr00 2019-06-10 21:03:01 UTC

When Latte-Dock is set to have an opacity of zero and become solid when touching window it stutters when changing states.

make Latte panel background painting more important

--I reversed the logic meaning that the Latte panel
background painting in more important than the Plasma
original SVG painting. That way the animations between
panels painting become smoother with no glitches

I think this is improved, please test again...

except that the plasma theme roundness heuristic must be updated in order to be improved for those plasma themes that do not provide (mask) elements at all...
