Description Jihwan Shin 2025-08-06 12:41:37 UTC

In Plasma 6.4.3, when a window is in fullscreen and I press Meta to reveal the panel, the panel briefly becomes larger and then shrinks. This only happens when Do Not Disturb is enabled.

After slowing animation speed, I confirmed that a notification-related icon (bell/DND indicator) briefly appears in the system tray during panel reveal, then disappears instantly. This causes the panel to resize mid-animation, creating a visible flicker/jump.

Steps to reproduce:
1. Enable Do Not Disturb.
2. Open a window in fullscreen mode.
3. Press Meta to reveal the panel.
4. Observe the panel briefly resizing during the reveal animation.

Expected result:
- The panel should appear at a consistent size without flicker or transient resizing.

Actual result:
- The panel grows slightly, then shrinks, due to a transient icon appearing/disappearing in the tray.

I can't reproduce this. Can you attach a screen recording that shows it happening?
