Tonic Trouble v1.1 US, area transition black screen

[Romano44]

Using RMG 0.6.6 with "parallel RSP" and parallel video plugin, at the beginning of game during slide levels/areas, transitioning between them(that is loading the new area) end up with black screen. Chance of it to happen is high, there are about 3-5 area transitions before going to another level(on foot) so if it doesn't happen at the very first one then usually second or 3rd.

I isolated problem to parallel, as both gliden64 and angrylion+ do not have these issues. Also, no custom settings that I tried helped, both for parallel video plugin or outside like SI DMA Duration etc. But other plugins simply did not had this issue.

I am on Archlinux using mesa drivers and AMD 6700XT.
