The entire screen freezes for about half a second about once every 1-5 minutes, it gets worse if I use it actively, switching applications, interacting with the menues alot etc.
I believe this is an issue with the automatic graphics switching. When I turn it off and run it off the dedicatied GPU, the issue seems to go away. Has anybody else experienced anything similar?
MacBook Pro 16", macOS 10.15
UPDATE:
It seems to me that this is an issue with the refresh rate of the display. I changed the refresh from 60hz to the 59.94hz, which is the default, and the issue seems to have resolved. Still an software issue apple need to fix with driver updates.
What I have found out is that if you go under Display settings and disable switching between the cpu graphics and the AMD 5500 so that it keeps running graphics using the AMD, you will not notice these freezeups anymore...
So I have disabled the switching and hoping / waiting for the next Catalina release version which hopefully solves this :)

I've still continued to experience this even when on the default refresh rate (59.94Hz). I have gfxCardStatus installed and haven't seen a correlation between card switching and freezes. But the integrated graphics card does seem to be the culprit, as I only experience momentary freezes with it. I ran all day yesterday on the discrete graphics card and experienced no issues. Back on integrated graphics today and I see a few glitches a few times an hour.
More info:
After the most recent update 10.15.3, I have not experienced any freezing/microstutter issues (about 2-3 hours of use). The system definitely seems more stable, so I am holding my breath that this did the trick. I read the update notes that this release featured new intel and amd drivers, so that that might have been the issue all along, but time will tell.
+1 I've the same exact issue on my macbook pro 16 inch and it all goes away once you switch to the dGPU only.
10.15.3 and this issue still exists and everything is sluggish as **** when I'm using the internal graphic card.
Luckily I'm plugged in all the time so I just keep it on the dGPU.
UPDATE 2:
This did not solve my problem after all.
I have tested 2 different models of the new MBP: base i7 and top spec i9. Both has the exact same issue.
I made a post about this on reddit as well. It gained some attention:
https://www.reddit.com/r/macbookpro/comments/e8ap54/several_issues_with_my_16_macbook_pro/
The issue is solved by running off dGPU as some people here has mentioned. But this introduces another isssue for me with the cursor jumping around when switching cursor types.

I really hope these issues can gain some attention from Apple soon.

You not seeing it does not make it nonexistent, just an anecdotal evidence.
Arguably your seeing freezes is the same, anecdotal.
If you can reproduce it, I would recommend you contact Apple, either via a Genius Bar appointment or via the Internet.
I have the same issue on my 16" MacBookPro with AMD Radeon Pro 5500M.
For me the duration varies, the display freezes anywhere from for 10 seconds - 2 minutes. If I am watching a YouTube video the sound will continue to play and the touch bar is responsive even when the display is frozen. It does recover automatically, but I have noticed that once I have the issue it will freeze again within within next 1-2 hour.
Thank you. I will definitely try that.
I called up Apple support, and as expected they are not aware of the issue. The support engineer asked me to try the following two solutions and report back.
When I shared the forum link, he also asked me to try the solution you have mentioned.
Will update here again.
Same here... So now I have enabled switching between graphic cards and also truetone...
So far i haven't seen any microfreeze problems yet - fingers crossed
But this introduces another issue for me. The cursor is jumping when it switches between pointer, hand, text selector. It is not an issue with the integrated graphics. Both modes is a nightmare for me...
Same problem here. Something is really wrong with the MBP 16 iGPU on Catalina :(
I am experiencing the exact same thing...
While scrolling inside Visual Studio code the computer stutters and switching tabs inside Google Chrome sometimes takes forever...

I do not see this at all and use my MBP 16 for such tasks daily.
I can't imagine what the difference is (no external monitor, though.)
