This bug happens just when V-Sync is off and attempting to open and close the home menu. To fix the black/frozen screen it's just enough to call the GX2SetSwapInterval(0); right after entering the foreground back.

P.S. I checked on the WUT side, and seems, such workaround is required since it's a bug of the Wii U firmware itself.

Unexpectedly, this bug affects the EasyRPG (ping @Ghabry to use the newer SDL2 for Wii U after this fix arrive) too when disabling V-Sync, and re-enabling V-Sync restores back the screen:
