echo "What was configured:"
echo "  ✓ WebView2 Runtime installed"
echo "  ✓ FL64.exe-specific WebView2 policy set"
echo "  ✓ Single-context rendering enabled (prevents flickering)"
echo "  ✓ FL Studio installer launched"
echo
echo "After FL Studio installation completes:"
echo "  1. Launch FL Studio normally"
echo "  2. WebViews (plugin store, samples, etc.) should work without flickering"
echo "  3. Only FL Studio will use this WebView2 configuration"
echo
echo "Troubleshooting:"
echo "  - If WebViews don't work: run ./webview2-env-setup.sh again"
echo "  - If flickering returns: ensure single-context rendering is enabled"
echo "  - Check logs with: WINEDEBUG=+loaddll,+webview2 wine FL64.exe"

Assumptions:

• Installers are present in the same folder
• this script is also present in the same folder
• Modify WINEPREFIX and WINEBIN before calling to reference actual paths if needed
• Might need to modify if the FL Studio installer gets updated, as it references exact .exe name; I may change that in the future so it accepts another env var OR autodetects though
