OutRun - Road glitches after stage 3

[shadowthehedgehogxxx]

After stage 3 in OutRun the road completely glitches out. The car and roadside object sprites still show properly but the road stays like this for the most part until the end of the game. This bug is apparent on both this core and the SuperGrafx core.

The core version is v0.9.38.7.

confirmed as of commit 5a2803f
happens on some specific branch i think (left-right-right for example)

well, it must be a game issue thing, since even mednafen pce has the issue. might be better checking if its already reported upsteam, if not best to be reported if its not a game issue

i cannot get a specific pattern to replicate the problem. sometimes it comes out, sometimes not. usually it starts happening on the last part of stage 3 before the checkpoint for stage 4

in any case, its an upstream problem
