Steps to reproduce:

• Create a general empty project
• Add Star component to 2D view
• Click fill color of the star component in Properties view
• In the color picker dialog, change fill type from Solid to Linear
• Select both gradient stops in turn and select some colors for those
• Close the color picker dialog
• -> Fill color looks correct in Properties view - Fill color preview, but it does not look correct in 2D view
• Changing to Radial or Conical sometimes works, but sometimes has this same issue.
