Mac run slowly with some software

[tonistar75]

Hi, I have a MacBook Pro Core i7, quad core, 2.5 with 16gb ram and Mac OS Catalina 10.15.4.

Hi use the DisplayPort to connect my primary monitor (I use also another thunderbolt apple adapter for a second monitor but it's all ok).

With some software I see that the Mac run slowly (and freeze sometimes without changing image on the screen and with a trail when I move). At this point I have to close Mac and start again but with some software I have this problems every time.

I have this issue for example with Imovie, or with software of my audio card or sometimes with Teams.

If I disconnect the display port the Mac run perfect and all the above apps go well!

Can I try the new beta drivers? Can I set something?
Thank you in advance
Toni
