A 64bit application on windows 10 crashes (the same compiled in 32bit not) within the nvd3dumx.dll, after the Windows Desktop Screen was locked and then unlocked.
The IDirectDrawSurface7.Blt() function returns DDERR_SURFACELOST - any next call to direct-draw (e.g. IDirectDrawSurface7.Restore() or even IDirectDrawSurface7.Release()) will block now and the process will crash about 20-30 seconds later within the nvd3dumx.dll.
This seams to be a regression, with version 341.96 this worked fine, with version 369.26 and newer we’ve got the crashes.
All our Nvidia graphic cards (K2000, K4000, K620, K610, K600, …) doesn’t work, the AMD and Intels are working fine.
The callstack is as follow:
nvd3dumx.dll!00007ff8f3667b82() → Exception: 0xC0000005
ddraw.dll!TrimNotificationCallback()
gdi32.dll!DxTrimWnfCallback()
ntdll.dll!RtlpWnfWalkUserSubscriptionList()
ntdll.dll!RtlpWnfProcessCurrentDescriptor()
ntdll.dll!RtlpWnfNotificationThread()
ntdll.dll!TppExecuteWaitCallback()
ntdll.dll!TppWorkerThread()
kernel32.dll!BaseThreadInitThunk()
ntdll.dll!RtlUserThreadStart()
Needing help - or even better a hotfix!
