I'm going to type my complaint in the same format that Adobe after effects allows me to work:

DaVinci Resolve, Blender and Unreal Engine, last month (these products get their own line because I don't have to wait for them nearly as much as I do for After effects now.
After Effects started doing this thing today where I can't use the machine or any other apps (including web browsing) while I'm rendering, because it feels like the NASA supercomputer I use to render these 6 layers of motion graphics feels like it's about ot explode.

We don't care about the new features if we are unable to use them. Stop ignoring the lag and crash issues that people have been complaining about since 2015.

I have encountered a weird bug. First, I thought it was a fault in the project, but today I created a new, blank one, added an empty comp and the white blob is back. It looks the same and its on the same position.
Since its repeating in a brandnew project, this is likely a bug.

Its only visible in 8bpc projects, all higher bpc, this blob is gone.
I haven't re-installed AE yet, since its a workplace station and the IT has to do this and also reinstall all plugins. During a working day, thats almost impossible.

Do you need machine specs? If so, can you tell me how to collect them?

Cheers, and stay healthy and creative!

Version 17.1.3 is no longer importing MPEG 2 Long GOP HDV 720P footage. I have older footage from a JVC GY HD250 that still opens in Premiere, but the After Effects project will no longer conform the footage. So, I open AE to check the project, to find that footage, and any MPEG 2 I try to import, will import without error, but only displays black. Brand new Wintel machine with RTX 2080 super card. Other AE projects work fine, just not ones with this footage. Any workaround? I don't even think I can re-render the footage in Media Encoder, as AE will eventually lock up when trying to handle the MPEG 2 footage.

Thanks

3D Camera 'Link Focus Distance to Layer' does not work. When initially linking the focus distance, it is set correctly. But as soon as you orbit the camera around an orbit null, the focus distance no longer stays locked to the focus layer. Also, and bizarrely, if the orbit null is deleted the focus distance resumes the correct lock. After a lot of experimenting and 2 completely useless and infuriating sessions with Adobe support (Adobe - your tech support sucks - I have NEVER had a satisfactory experience with your tech support), I discovered that the problem appears to be with the new JavaScript Expressions Engine. If I select File/Project Settings/Expressions tab and choose Legacy ExtendScript instead of the default JavaScript, the problem goes away.

I have been working on a project for 10+ hours. It uses nested compositions and expressions referencing between compositions. One of the expressions is a for-loop that runs the sampleImage() expression four times - this expression in particular seems to be causing a lot of problems and throwing "internal errors."

The project has reached a point where it loads fine if all expressions are disabled - the preview updates immediately when I move the time indicator - but as soon as the expression is activated the property color changes from blue to green and hangs there instead of turning red. The preview freezes on that frame and will not update when the time indicator is moved. Other compositions do not update. If memory is purged the preview window becomes empty gray instead of showing a video frame or black screen. In Task Manager, Memory Usage constantly rises until it reaches the cap set in AE.

I've updated to the most recent AE build, graphics card driver, and version of Java, and I've fiddled with memory allocation and Secret settings. Nothing's fixed the problem so far.

When playing back only the audio on the After Effects timeline, the beginning of the audio is cut off and it can not be played back properly.
How, if you play video and audio simultaneously, you can play audio normally.

This happens even if the composition has only an audio layer.

You can confirm that After effects are playing in real time from the information panel.

The environment of PC is as follows.

Windows Main PC
CPU: Core i7-8700K
Memory: 32GB
GPU: RTX 2080
After Effects: CC2019

Windows Sub PC
CPU: Core i7-7700K
Memory: 32GB
GPU: GTX 1080 Ti
After Effects: CC2017

There is also another serious problem.
When you play a video on the timeline, the playback frame may be swapped, the video preview may be broken, or the image may be broken.
If you look at the information panel, you can see that is playing in real time, but it has not been able to play normally.
But, when loop playback is set, the second and subsequent playbacks are normal.

I have two Windows PCs, but the same thing happens on both PCs.
What is the cause?
