TotalSpace2 very slow when running Microsoft Office (Word, Excel, etc)

I have a MacBook Air (Retina, 13-inch, 2018) running Catalina 10.15.2 (19C57) and TotalSpaces2 works great except when I’m running Word or Excel. Once I start those up the whole system slows down and changes applications takes 30seconds.

If I quit TotalSpaces2 (but leave Word running) everything is fine.

Any ideas?

Only thing I can imagine is lack of memory, that there is pressure on the memory from both applications - TotalSpaces2 requires a quantity of memory to perform its animations and maintain the overview grid.

If that’s the case I don’t know what can be done, perhaps try turning off animations in TotalSpaces2?
