We should look to see if they should be run with ui scale of 1,
or if they are telling us of one or more product bugs.
Comments
AWT components do not handle High DPI well, there are discrepancies in size here and there, it's likely the reason why these tests fail in High DPI environment. So, I'm sure AWT tests fail because of the product bugs. Swing handles High DPI, as such failure of Swing-related tests could be due to a minor difference in rendering.

java/awt/PopupMenu/PopupMenuLocation.java fails because of JDK-8259913 (= JDK-8310641). On a 4K display with 200% scale, the robot fails to click a menu item in the popup menu because the mouse is moved too far. Robot coordinates are scaled, but the height of the menu items isn't scaled up, their height is the same as in the 100% scale case.

[~prr] can you please give the mach5 job for javax/swing/plaf/basic/BasicComboPopup/JComboBoxPopupLocation/JComboBoxPopupLocation.java failure ? I ran several iterations on mach5 on all 3 platforms without failure. https://mach5.us.oracle.com/mdash/jobs/prsadhuk-jdk-20201005-1717-14701063?search= If it is not failing now for you too, can you review https://github.com/openjdk/jdk/pull/535?

The same tests fail on macOS when HiDPI is enabled.

remember to remove java/awt/Mixing/AWT_Mixing/MixingFrameResizing.java java/awt/Mixing/AWT_Mixing/HierarchyBoundsListenerMixingTest.java from the problem list in the fix for 8221823

Sounds fine. I made it one in case you just needed to add a uiScale=1 to all of them

This is umbrella bug, I'll file a separate bugs per product issue.

These: java/awt/Mixing/AWT_Mixing/MixingFrameResizing.java java/awt/Mixing/AWT_Mixing/HierarchyBoundsListenerMixingTest.java will be fixed as part of, will send it today https://bugs.openjdk.java.net/browse/JDK-8221823
