Summary	08222: racedriv: Graphic glitch (flowers in the sky)
Description	In "Race Drivin" on the "Original Track" driving down the trough sometimes shows flowers floating in the sky. This does not happen in "Hard Drivin". Is this a Slapstick emulation bug? If yes, may be symptom of more severe problems (e.g. related to the excessive skidding bug #08214) and thus should be investigated. The Hard Drivin series generally has a zillion of strange graphics glitches (also see #03117), but while most I suspect to be authentic original game bugs, the "flowers in the sky" seems to be a MAME bug that (according to youtube videos) does not occur in the original arcade game.

No.19809 Tafoid Administrator Feb 20, 2022, 09:26	When posting issues regarding graphics, you need to provide snapshots (taken with F12 within MAME, before any shader processing) and also a reference video/snap of how it is supposed to look is helpful too. Not providing some basic images to detail what you are saying isn't helpful to help duplicate and causes us to do all your research for you.
