Anyone experiencing UI issues with Excel Labs?

For a while, the Excel Labs add-on seemed to work fine for me. For a few months now I've been getting a lot of stuttering issues in Excel. These make the UI slow and unrensponsive, but have nothing to do with actual calculations being executed; just clikcking or moving through cells becomes laggy.

If I close the workbook and open it again it fixes itself, but going through that multiple times an hour feels wrong.

Any tips? I really like the advanced formula enviroment and kinda don´t wanna uninstall it.
