Error 83::2 - String Memory Leak
I get this error message every time I log out of AE 2019 whilst using one particular project that involves a lot of imports. Will not open the files again later. I can work around it by importing the file into a new project, but once I save the NEW project, under a different name and go to quit the program, I get the same error message and rinse and repeat. I don't know which, if any, files are corrupt and the program otherwise acts normally until I try and close out the program.It doesn't generate an error report or anything, so I can't access that. When I try to reopen, whatever the error is causes the files to open part way, and then the application stops responding. Any thoughts? I've lost HOURS of work on this project every time.

I love the new drop down expression control effect in AE2020. Unfortunately though I have a bug on opening the project file. I get a dialog box similar to the attached screen grab for each instance I've used the drop-down menu as a master property. The code in the dialog changes for each instance.

For context, my project file features one precomp with a number of properties controlled by 3x dropdown menus on a control layer for colour, text option and positioning. That precomp is used in 5 other compositions, where using Master Properties I have used different drop down options for each. That means on opening the project file I get this dialog box 15 times (5x3 = 15).

It also doesn't save my previous combinations of master properties across the five comps, instead it will default back to whatever is the first option in the drop down – so I need to reset with every time I open the project, regardless of saving the project file.

In a 1080p comp, a shape layer is animated in position, the RAM preview is slow/laggy and play aorund 19-20 fps instead of 25.
But if I scrub the timeline, everything is smooth, reactive.
See the video attached, What can I do ?

Having an issue with the new 2020 update that was not happening with 2019. First off, a lot of things are quite laggy when clicked so take a long time to react. Sometimes it's a second or two, sometimes it's so long I start thinking AE is locked up. I can start playback on a section and then it won't stop (by hitting 0, clicking the playhead, hitting Space). Sometimes it takes a few seconds to respond and sometimes up to a minute. Several times now I actually had to force close AE just to make it stop playback.

I updated the P5200 driver as I saw nvidia posted a new driver three days ago. This didn't affect the AE issue though.

Since updating to the latest build of AE (16.1.2 Build 55) my ram previews are again unstable at best (a problem I haven't had with a number of previous AE builds).

If I open a project that has a number of other reduced AE projects that have been imported into that project, my RAM previews stutter like crazy and the feature is basically unusable (again, a problem I haven't had with a number of previous AE builds… I’m so disappointed to see it return).

If I reduce that project, I can get an almost useable RAM preview, but there’s still a slight stutter to the preview.

I searched for a solution online, and someone suggested that if you have a pull-down menu selected during a RAM preview, you’ll get a smooth, real-time preview… and sure enough, I tried it and it worked—but as soon as I deselect the pull-down menu, the preview becomes stuttery and falls well below real-time. That tells me pretty definitely that this is a problem with the build... not the machine or my project.

Again, with the build before this most current one, RAM previews were pretty flawless. Please help!

As I said, I’m using the most current build of AE. Also, I’m using a Mac Pro (Mid 2012)(OS 10.13.6), 12 core, 64 GBs of RAM, with a Nvidia GeGorce GTX 980 card.

Thank you!
