PCSX2 Front Mission 5: Scars of War - weird shadows glitch

Wanzers have multiple shadows underneath them when playing this game in PCSX2 emulator. These shadows appear and disappear, depending on how many wanzers are present on screen, it seems. Everything else is a-ok, that's the only graphic-related problem i've encountered. Tried everything; changing graphics options, resolution, turning on / off hacks, nothing helps. Only way to deal with this glitch is to play game in software mode, but then game looks awful. I've seen this glitch in many other videos, from FM5 played in PCSX2 emulator, on YT. Has anyone maneged to get rid of this problem?
