Confirmed! We're always happy to help with development. 🙂 May I ask what the exact cause was? I actually assumed that the Amiga/AGA emulation of WinUAE is almost complete. It would be interesting to know where the differences from the original were in this case. Greetings and Hugs from Germany! 🤗
It was some code for fading out panels that slipped through testing, as it does not cause an issue on the kick-start that comes bundled with WinUAE but hangs on real Commodore Kickstarts.
