--- Comment #6 from Tony Crawford tonybcrawford@gmail.com 2012-09-16 14:35:14 CDT --- I see that changes since wine 1.5.12 include the following: gdi32: Move the SwapBuffers entry point to the OpenGL driver. Perhaps this is related to the OpenGL display error on wine 1.5.13
Further observations (related to the same problem): 1) Screen re-size makes the entire display grey - zoom-in or view rotation corrects the display. 2) Selecting a menu option creates a large grey rectangle on the display - zoom-in or view rotation corrects the display. 3) The SDET application's print screen now produces a completely grey output. NB: I have seen a similar problem on Windows 7 when using Aero... in that case it can be corrected by disabling 'Desktop Composition'.
