Bug ID: 49817
           Summary: d3d9: Crashes on invalid opengl context with disabled
                    csmt in IDirect3DDevice9Ex_CreateOffscreenPlainSurface
           Product: Wine
           Version: 5.17
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs@winehq.org

test that shows invalid error handling on invalid opengl context
The simplest way to reproduce the crash is (I was only testing it running
32-bit process):
 - disable csmt
 - run the test with WINEDEBUG=warn+heap (to guarantee the crash)
The test destroys window/hdc used by current gl context. After that it's not
possible to restore previous context in Direct3DCreate9Ex. It also leads to a
crash when deleting "destroyed" context in
IDirect3DDevice9Ex_CreateOffscreenPlainSurface.
