Scintilla interferes with viewport display

[Josh]

Once any code file is opened in the script editor, the main window viewports can no longer resize correctly.

This happens if the script editor window is parented to the main window, or if it is a top-level window.

Nvidia GEForce 1080 TI, driver 32.0.15.7688.

The issue seems to be caused by this line of code, which is used for the Scintilla widget control:

SetWindowLongPtr(hwnd, GWLP_WNDPROC, (LONG_PTR)SyntaxEditor::CustomWndProc);

I even tried creating the script editor window from a separate Win32 window class, but it made no difference. It looks like this effects all windows created by this process. My guess is it has to do with the Nvidia overlay.

Using SetWindowSubclass() instead does not solve the problem.

This even happens if I add WS_POPUP to the Scintilla window style and create it with a NULL parent, and set hInstance to NULL.

No issues when testing with an AMD 6600.

This actually has nothing to do with the window subclassing. Simply creating a Scintilla window in the program is enough to corrupt the 3D windows.

Issue is solved. It was my error.
