DirectX 9 fullscreen - no input and no way to exit

[SlowRichard]

Under Beebem v4.18 on Windows 11, if I enter fullscreen mode with the following settings (I believe these are the defaults) then there appears to be no way to exit fullscreen except signing out or shutting down.

Display Renderer: DirectX9
DirectX Full Screen Modes: 640x480
Method: either Alt+Enter or View-Full Screen menus

Changing the DirectX Full Screen Mode to Current Screen Resolution "fixes" this issue.

I hope this helps.

Thanks,
Richard

Thanks, I don't have Windows 11 to test with, I'll see if I can reproduce this on Windows 10.

Hi,

Thanks for looking into this but I have tried to reproduce it myself just now with the same settings and everything seems to be working fine now!

I know it happened consistently before, I'm not sure what else has changed on my system (no graphics drivers updates, a couple of Windows cumulative updates) but something seems to have sorted it...

Thanks again,

Richard

Hi,

Sorry I spoke to soon, I tried one more time after posting and of course it crashed like before.

For what it's worth, I just tried installing Beebem on my laptop (Intel with Xe integrated graphics) and couldn't reproduce it. The desktop/mini PC I was using has a Ryzen with Radeon integrated graphics, so it could just be a driver issue... Anyway, it's easily fixed by setting the fullscreen resolution to match the desktop.

Thanks,
Richard

Sorry for the delay in replying.

On my laptop, with DirectX9 selected, and any screen mode other than "Current Screen Resolution", entering full screen causes BeebEm to enter a loop continually resetting the screen mode. It seems to be caused by a D3DERR_DEVICELOST error, handled here:

beebem-windows/Src/beebwindx.cpp

Line 520 in 917bced

ResetDX();
