Tyra have old bug caused by (probably) timing issues between EE <- VU -> GS.
It cause texture flickering / corrupted texture on the model.
It is visible on skybox-debug sample (skybox flickering), de_dust2 (doors) and demo (skybox black areas).

We had workaround in PCSX2 1.6.0 for this issue.
It was EE timing hack which resolved this issue.

I don't see this feature in new version of PCSX2, so this bug should be resolved ASAP.
