            Bug ID: 59295
           Summary: GOG Galaxy: Maximising the window causes graphical
                    issues
           Product: Wine
           Version: 10.19
          Hardware: x86-64
               URL: https://gogalaxy.com
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When GOG Galaxy is maximised by using the button in the top right corner (or
another way to do so), it shows a mix of the content from before maximising the
window, a black empty area, and a white border.

When maximising the window, this is written to the log:
"0120:fixme:dwmapi:DwmExtendFrameIntoClientArea (0001013C, 0022DA90) stub"

Before maximising the window, another message is written multiple times to the
log:
"0254:fixme:dxgi:d3d11_swapchain_Present1 Ignored present parameters 0022F120."
This pauses for a while after the window has been maximised.

After some time, or when the "Update available"-pop-up appears, some parts of
the window can begin to flicker.
While the flickering happens, these messages are written multiple times to the
log quickly:
"0254:fixme:dxgi:wined3d_bind_flags_from_dxgi_usage Unhandled DXGI usage 0x40."
"0254:fixme:dxgi:d3d11_swapchain_Present1 Ignored present parameters 0022F130."

Occasionally, the flickering can stutter once for less than half a second, and
the following message is written to the log:
"019c:err:d3d:wined3d_context_gl_set_pixel_format wglSetPixelFormatWINE failed
to set pixel format 81 on device context 00000000."

One can use the Super-key and then move the window, or hold the Super-key and
then open the context-menu (usually by clicking with the right mouse-button),
to restore it from the maximised state.
