[PATCH 0/1] MR1928: dwmapi: Fill qpcVBlank in DwmGetCompositionTimingInfo().

[Paul Gofman (＠gofman)]

Since commit 182feddd4b02e83f3c69863bc2e6e63945eb2df1 DwmGetCompositionTimingInfo() returns success. Currently wine-gecko fails to display anything if prefix version is Win10. That is due to zero qpcVBlank field in DwmGetCompositionTimingInfo() output which is currently missing. Before the referenced commit it was handling the failure (see gfx/thebes/gfxWindowsPlatform.cpp:VBlankLoop() (line 2840 in the current wine-gecko snapshot from https://sourceforge.net/p/wine/wine-gecko/ci/master/tree/).
