Using dgVoodoo2 v2.79.3 resolves crashing I get with Sacred 2 when I try to run it with VSync, but I noticed some minor HUD issues:

1. Icons of equipped combat arts (big circles to the right side of the compass, at the center-bottom of the screen) become corrupted when a HUD window is opened (e.g. inventory window, character sheet, combat arts window)
2. Icons of equipped combat arts buffs (small circles at the bottom right corner of the screen) don't have color
3. Icons of combat arts in the combat arts window are corrupted (in the screenshot, only three of the icons under the "Revered Technology" category are corrupted) Also, the progress meter for combat arts appears broken (for the same category in the given screenshot)

Compare the two screenshots, the first is taken with dgVoodoo2, the other is with native:
