Progress Bar on App-Switcher and Doc icons does not update correctly

The progress bars on the Premiere Pro and Adobe Media Encoder icons in the macOS Dock and Command-Tab app switcher no longer update correctly during processing.

The progress bar appears when an export or render starts, but remains almost empty until the operation finishes. It then disappears and the icon returns to its normal appearance.

The progress indicator inside the application updates normally, and the operation completes successfully. This appears to be a progress-display issue rather than an export or rendering failure.

System information

• Premiere Pro: 26.5.2 (Build 5)

• Adobe Media Encoder: 26.5.2 (Build 2)

• macOS: Tahoe 26.7.1, Build 25G241

• Computer: MacBook Pro, 16-inch, 2021

• Chip: Apple M1 Max

• Memory: 64 GB

• GPU: 32-core

• Display configuration:

  • Apple Studio Display connected via Thunderbolt

  • Dell P2720DC QHD display connected via HDMI

Operations affected

I have observed this with:

• Direct exports from Premiere Pro.

• Exports processed in Adobe Media Encoder.

• Timeline preview rendering in Premiere Pro.

Steps to reproduce

1. Start an export directly from Premiere Pro.

2. Confirm that the progress indicator inside Premiere advances.

3. Inspect Premiere’s Dock icon.

4. Hold Command-Tab to inspect its icon in the macOS app switcher.

5. Compare the icon’s progress indicator with the progress shown inside Premiere.

6. Repeat with an export queued to Adobe Media Encoder, inspecting Media Encoder’s icon.

7. Repeat with a timeline preview render in Premiere.

Use an operation long enough to observe the progress changing inside the application.

Expected result

The Dock and app-switcher progress bars advance throughout the operation, broadly reflecting the progress shown inside the application.

These indicators previously provided a useful way to check progress while working in another app.

Actual result

The icon’s progress bar appears at the start but remains near its initial position for the entire operation, even as the application’s internal progress indicator advances.

When the export or render finishes, the icon’s progress bar disappears.

Impact

Exports and renders complete successfully, but the external progress indicators are misleading. I frequently use Command-Tab to check processing progress without returning to the application, and that is no longer reliable.

Regression / frequency

This worked reliably in the past and now occurs with both exports and timeline renders. I have not isolated the last working application or macOS version.

The recording demonstrates the export-progress behavior in Premiere Pro and Adobe Media Encoder. I also confirmed the same behavior separately while rendering a timeline in Premiere.
