New area not refreshed after increasing RTG window size

[mark_k]

In uaegfx RTG mode with "Always Center" off, you can increase the size of the emulation window but the RTG display remains at the top left of the resized window, with "trash" in the newly-exposed parts. Dragging another window over the emulation window leaves trash in the newly-exposed areas. Also, if you un-capture the mouse and click in a newly-exposed part of the window, the mouse is not captured. You have to click in the RTG area being refreshed in order for the mouse to be captured.

Happens with WinUAE 2.6.0b1 and later but not 2.5.1. With 2.5.1 (which doesn't have the Always Center option) on increasing RTG window size the newly-exposed parts are black and dragging another window over it doesn't leave trash. Clicking in the newly-exposed area does capture the mouse.

Window resize shouldn't be active in RTG modes unless center or scale options are enabled. Resizing is disabled here if centering is off.

Ah thanks, this looks like a bug/issue with Wine. When not using Wine's virtual desktop mode it seems the window isn't prevented from being resized.

Edit to add: How does WinUAE handle disabling window resizing? Does it get a message from Windows saying "the user is trying to resize you, is that okay?" which you then reply no to? Or do you set the window's minimum and maximum size to the same dimensions?

I noticed a similar issue with Wine before; when not in virtual desktop mode Wine doesn't know when the user is about to resize the window so can't send the appropriate message. Thus when Resizeable GUI is enabled, WinUAE doesn't re-layout the controls because it can't detect the window has been resized. So this could possibly be worked around by setting the emulation window min and max sizes to the same dimensions to prevent resizing.
