Upgraded to java 19 on Windows 10.

Noticed that after coming out of sleep mode (overnight), some of my Swing applications do not get repainted, showing empty panels instead (screenshots to follow).

Dragging other windows over the affected applications produce no change, but minimizing and subsequent restore does help.

works correctly -
jdk-11.0.16.1
jdk-17.0.5
jdk-18.0.2.1

fails -
jdk-19.0.1
jdk-20
