WinUAE 2.5.0 graphics API change issue with A2024 modes

[mark_k]

Note that I'm testing using Wine, but this issue doesn't look Wine-specific.

If the current screenmode is an A2024 mode and you change the graphics API (open settings window, in Miscellanous page) from Direct3D to DirectDraw, WinUAE seems to forget the special mode and clips/centres the output window assuming a native PAL/NTSC mode.

You can recover things by bringing a native screen to the front and back, then WinUAE correctly shows the A2024 display again.

Attached log is for this:

• Start emulated (PAL) Amiga, boots to PAL high-res laced Workbench.
• Run (NTSC-patched) A2024 monitor driver.
• Set Workbench to A2024:15Hz 1024x800.
• Run Imploder (which opens a PAL high res custom screen).
• Put Imploder screen to back. The A2024-mode Workbench appears correctly.
• Change graphics API from Direct3D to DirectDraw.
• The A2024 display appears incorrect, clipped to the normal PAL/NTSC size, see pic.
• Put Workbench screen to back so Imploder PAL screen to front. That appears correct.
• Put Imploder to back. A2024 Workbench appears correct again.

Update to add: This issue also happens if you change the window style, e.g. from standard to extended. So it's not specifically related to the graphics API, more to when WinUAE closes and re-opens the emulation window.

Confirmed and will be fixed.

I believe this also happens when in A2024 display mode and switching between Full Screen and Windowed mode.
