Live dashboard tiles flickering

The problem started quite recently and I tried to roll back all of the changes that were made to the real-time dataset, but it made no difference. The only thing that was added back then was just one column and a simple measure. Also, to optimize the visualizations I also made some quite substantial reductions to the imported dataset that is being visualized in the same dashboard. The whole dashboard is now much "lighter" than what it used to be, but the problem persists.

Also, it's weird that Power BI re-renders all of the tiles and resets all of the slicers, regardless if they are using different datasets (the other being updated every minute and the other every three hours).
