Pen Latency on whiteboard while recording

[sea_echo]

I've never had this problem before and don't know if it's a Zoom update or maybe a driver update on my Wacom tablet.  The pen writing on the Zoom whiteboard was always smooth and seamless and I could write as fast as I wanted.  Now for some reason, at least while recording the meeting, I have to write super slow or it just looks like scribbles!  A one-hour lecture turned into two!  Very frustrating.  It's strange, because I think when not recording it still works well, but I haven't quite been able to identify the problem.  Please help!

BTW, I do notice that Zoom is using a high amount of memory (6.67GB), but don't know how to stop that.

Version: 6.3.11 (60501)

Update:  I tried switching to the Classic Whiteboard, and that seems to have remedied the problem.  Still not sure why, and I'd prefer to use the newer whiteboard if I can get it to work!
