I am doing the necessary tests. It seems like for the default Look ad Feel (Aqua) of Macosx an extra `setOpaque(true)` is needed. If the test test/jdk/java/awt/Mixing/AWT_Mixing/MixingPanelsResizing.java uses metal look and feel, `setOpaque(true)` is not needed and the test passes. I have updated the MR accordingly. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/26625#discussion_r2279554425
