Issue with Intermittent Blank Visuals in Power BI Despite Successful Refresh

Hi everyone, I'm facing a strange issue with my Power BI reports. At times, the visuals and cards on my report appear blank, while at other times, they are populated correctly. This happens both in the Power BI Desktop and the Power BI Service (where I have scheduled refreshes every hour).

The refresh status always shows as successful with no errors, but the report/dashboard still displays blank visuals occasionally.

Some additional context:

The data source is PostgreSQL

I’m using an on-premise data gateway for the scheduled refreshes

Has anyone else experienced something similar or know what might be causing this? Any help would be appreciated!
