Dashboard Rendering Issue – Existing Dashboard Tiles Changed

Hi lubomirpokorny​ ,

Thank you for reaching out to Microsoft Fabric Community Forum, Below are the few points which can resolve your issue. Let us know if you need any further assistance.

Based on your observations, this behavior appears consistent with a known Power BI Service issue affecting the rendering of chart plot-area backgrounds on dashboard tiles. Microsoft has acknowledged a similar issue and indicated that a fix is in progress.

• Test with a new dashboard: Pin one affected visual to a test dashboard and check whether it renders correctly.
• Verify dashboard theme behavior: If the issue persists, review the dashboard theme settings under Edit → View → Theme. You can also test the available tile theming options, where supported, to compare the report theme with the dashboard theme.
• Avoid unnecessary republishing: Since the underlying reports render correctly, republishing them or changing their visual formatting may not resolve the issue.

Thanks,
Chaithanya.
