Hey all,
I've been dealing with a bug (albeit by using an older version) for about two years now. I'm starting to get fed up and want to compose a complaint to avid, but don't have tons of data outside my realm of accessible computers.
The gist is that– the more clips a session has, the slower the session will start to behave. Simple as that.
—and if this doesn't sound like a bug to you, try it on both ≤2019.6 and ≥2019.10. There's a huge difference in the way Pro Tools behaves.
Here's a session (about an hour of white noise at 44.1/16) to replicate it: (If you don't want to download, let me know and I'll write out the steps in another response.)

As far as I know, if you're using anything above 2019.6, Pro Tools will slow down to an almost unusable state by step 3. If not, add another hour of audio to the "Step 1" track and try again.
Please let me know your operating system, specs, Pro Tools version, and whether or not you felt the bug.
*EDIT - Please see response #5 below for a more detailed explanation.
