I downloaded the beta version and it dosen't have this problem any more!!☝️✨

@JohnColombo17100380 
last beta update now doesn't have the black comp screen problem, but the UI lag came back again.

@JohnColombo17100380 
for the release version, I get only the UI lag problem.
in the beta, I get only the black comp problem.
I was using mercury gpu acceleration and I tried to switch it to software, but the blackcomp problem still occures.

Thank for that update, @ahmed hamed elsaid. Does the release version also show the black comp windows now, or does it only show the UI lag?

Additionally, is your project using Mercurcy GPU acceleration in the Project Settings under Video Renderer? I would wonder if this is related to a GPU driver version.

Thanks again,

@JohnColombo17100380 the problem still exist unfortunately😭.

Hi @ahmed hamed elsaid, thank you for patience and for mention.

In looking at your specs and the log file, I see a couple possible culprits for the slow down. Please try the following and let us know if it makes a difference to the lag:

1. There is at least one ScriptUI panel being loaded when After Effects starts. If you remove that panel from the workspace, does the performance improve?
2. Separate from the script, does AE's UI performance improve if you disable your internet device or disconnect from the internet?

Thanks again for your patience,

- John, After Effects Engineering Team
