Warcraft 3 v1.26a
WC3_FPSUnlocker mod
dgVoodoo2 2.82.3

Whenever is use dgVoodoo2 together with WC3_FPSUnlocker - the game no longer recovers from Alt-Tab. No such issue if I use dgVoodoo2 or WC3_FPSUnlocker alone. What could be causing it and how can it be fixed?
I did ask the author of WC3_FPSUnlocker about this bug, but he brushed it off as a dgVoodoo2 problem.

Tested again with dgVoodoo2 2.83.1 with debug logging enabled. Looks like the game tries to re-create swapchain with 500Hz refresh rate, somehow it works on native d3d8 but fails in dgVoodoo2.

no need to use dgvoodoo, 1.26 has an opengl renderer that works fine.

That's what I've been using in the past, but stopped after observing graphical corruption in some custom campaign maps.
dgVoodoo2 seems to deliver better performance than native OpenGL renderer + it has an ability to force borderless windowed with custom scaling, so I can play the game in 4:3 and still have seamless Alt+Tab.
Anyway, I've already worked around this issue by overriding refresh rate via dgVoodooCpl.
