I'm getting boxes rendering all over the place. It happens “lightly” when navigating around, but it’s particularly “heavy” when Figma is doing some heavy lifting - like using the AI agent.

Screen shot of the bug in action:

Steps to reproduce:
1. Open Figma desktop
2. Run an agent task like - replace copy with lorem ipsum.
3. Black boxes appear over elements, or the panel shows content behind it instead of a solid background
Expected: UI renders cleanly with solid, opaque panels and no black box artifacts
Actual: Rendering artifacts as described above
Troubleshooting already done:
- Reproduces on a fresh macOS user account with only Figma installed, so it's not caused by another app, extension, or corrupted preferences
- Reproduces in Safe Mode
- Happens on both the internal display and an external display
- Updated to the latest version of Figma desktop, issue persists
System:
MacBook Air 13-inch, M3, 2024, 8GB unified memory
macOS 26.5.2 (25F84)
