The BitMapInverseWipeScalar Execute passed the colour constants as DrawBitMap's first argument; the sibling wipe always passes 0 there (colour selection is SetColor only). The nonzero arg smeared striped garbage across the weapon MFD pages from the gauge's first draw (operator's capture.png). Pixel-verified clean after the fix (weapon pages pristine, eject graphic path unchanged). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
