I'm not sure why this is different.
Can you point to the code where it uses PeekGraphics in Nimbus/Aqua and the subsequent code from where is starts to bifurcate in other L&F meaning where it starts to uses PeekGraphics for Nimbus/Aqua and PathGraphics for others? ------------- PR Comment: https://git.openjdk.org/jdk/pull/18187#issuecomment-2036938917
