Hello, I've recently been experiencing massive interface bug issues with After Effects 26.3 on my Mac Pro M5, 32 GB. The interface seems to disappear and reappear all the time, it's simply unusable!

Hi Harry, thanks for the update. This isn't your bad. Having to unplug a secondary monitor to make AE usable is definitely not ideal.

Some details that would help diagnose this properly:

1. Your macOS version.

2. Your secondary monitor model, connection type (HDMI, USB-C, DisplayPort), and resolution/refresh rate.

3. Is your secondary monitor set to Mirror or Extended display?

4. What happens if you toggle off "Hardware Accelerate Composition, Layer, and Footage Panels" (Preferences > Appearance)? Does the interface behave normally with the secondary monitor plugged in when that's off?

Rolling back to 26.2.1 via Creative Cloud (three dots next to After Effects > Other versions) could be workaround while we get this addressed.

Let me know how it goes.

Thanks,

Nishu

Sorry quick update for this, it seems to actually be linked to a secondary monitor I’m using, when unpluged the interface behaves normally!! My bad
