I'm experiencing an issue with AetherSDR, a Linux/macOS/Windows SDR client
for FlexRadio transceivers (https://github.com/ten9876/AetherSDR).

My system:

• AetherSDR version: 0.9.6
• Qt version: 6.11.0
• OS: macOS
• Radio: FLEX-6400 fw 4.1.5.39794

Before writing the bug report, please read the AetherSDR project context at
https://raw.githubusercontent.com/ten9876/AetherSDR/main/CLAUDE.md
for architecture overview, data flow, protocol details, and known issues.

Based on my description below, write a complete GitHub bug report.
Do NOT ask me follow-up questions — just write the best report you can
from what I've provided. Output it in one response, ready to paste.
Use GitHub-flavored Markdown formatting (headers, code blocks, bullet points).

Format it as:

Developer Notes

(After reviewing the codebase, suggest which source files and functions
are most likely involved, what logging categories to enable in
Help → Support to capture diagnostic data, and any potential root causes
based on the code architecture. Reference specific file paths and line
numbers where possible.)

Here is my issue: minimal mode is not working, application goes small and returns to normal size.

about 10 minutes" or "Audio cuts out when I switch bands"]
