DP 10 Window Lag

[ScrumpyArbuckle]

Hi all. I've scoured the internet and can't find any info on the problem I'm having.

When I drag or resize any window in DP 10, there is a considerable lag of about .5 - 1 seconds. The cursor is in position before the window is. I am at a loss as to what is causing it. This slows down my work and is quite frustrating, especially when fine tuning window size is necessary. It doesn't matter what kind of session I have open - this occurs with empty templates as well as fully tracked sessions.
My gear is simple:

16-inch MacBook Pro 2019
2.6 GHz 6-Core Intel Core i7
16 GB Memory and an SSD

running the latest version of Catalina, 10.15.4 along with the latest version of DP, 10.11.

Any ideas would be greatly appreciated!

Thank you.

I've seen this behavior in a program called Plugin Doctor but not in DP. The problem only exists when I boot from my Catalina partition, but not from Mojave. Perhaps it's not a DP problem but a Catalina problem. Don't know.

Thanks, Phil.

I truly do not know what is happening. I've searched the archives on this forum but so far have not found anything similar.

You might try a safe boot procedure to clear your cache.

Thank you MLC,

I tried that with high hopes, but no go. Good idea though, as I have forgotten such procedures!

Could this be it?
