J2DDemo - Images tab - DukeAnim demo - rendering vanishes based on options in Global Controls

Run J2DDemo with Metal pipeline. Go to Images tab. Double click on DukeAnim pane (top-left demo pane)

On right side, there are global controls.
Below behavior is observed - with or without AA rendering.
1) Select 'Rendering Quality' checkbox - Animating duke image vanishes (only with default scale on Retina display, not reproducible with uiScale=1.0 on retina display)
2) Select 'AlphaComposite' checkbox - Animating duke image is visible but background image vanishes - (with default scale and also with uiScale=1.0 on retina display)

Tested on Catalina (10.15.4) + Retina display.
