Lens flare effect green flash, corrupt FMVs

[71knight]

Game or games this happens in

Burnout dominator, need for speed shift, maybe more

What area of the game

During full motion videos before racing, also lens flare has green boxes in it briefly.

What happens

Full motion videos have digital artifact errors/ random digital error squares, sometimes almost covering complete screen. Lens flare has momentary green squares in it. Best seen when viewing car model at car selection screen and rotating car. I believe the developer said this was caused by not implementing Z-upload.

What should happen

Videos should play back perfect. Lens flare effect shouldn't have green boxes in it briefly.

Checklist

• Test in the latest git build in case it's already fixed.
• Search for other reports of the same issue.
• Try resetting settings or older versions and include if the issue is related.
• Try changing graphics settings to determine if one causes the glitch (especially speed hacks or enhancements/replacements.)
• Include logs or screenshots of issue.

I don't know how the effect is related to FMVs, but who knows (oh, these are actually not full motion video, it's rendered the same way as in-game).

Green flash is known, and I do plan to fix it of course.

OK, not only was checking the CLUT usage flag of the framebuffer not reliable (of course, one frame late), but we end up resizing the clut framebuffer immediately after creating for some reason, which loses the just-uploaded z buffer. Fixing that.

Oops, looks like I broke this again in #16072 . Many moving parts.. Should be an easy fix.

Sorry for bad news but sunspot is visible through mountains and tunnels.

Not for me on PC. But I'll take a look on Android. Thanks

What backend?

Nevermind....the sunspot is fixed along with the lens flare in the latest build. The full motion video is still corrupt in burnout dominator and need for speed shift. The problem appears to be because of live rendered graphics (X and O button, options, etc.) over the full motion video background and the buffers aren't playing nice with each other I guess. I played a full motion video with no graphic overlays and it played perfectly. I even tried another ISO of the same game and it still was broken. Maybe the lens flare and sun fix had something to do with it maybe? Great job on fixing the lens flare and sun occlusion.

Thanks. I don't understand which FMV is looking corrupt though, can you make a screenshot, or tell me which one and how to get it to play?

[71knight]

On need for speed shift you can see it when you're selecting different options in the menu before a race.
You should see the background glitch when selecting options at the beginning of the game.

Alright, that kind of glitch is, while definitely a bug, definitely unrelated to the green lens flare and similar.

NFS Shift does seem to have other issues though. The bloom is horribly ugly although that's an artifact of resoultion, and gets better with "Lower resolution for effects". However, billboards in the game seem to be textured with noise or grass or something, that can't be right.

I've just watched this game being played on a real PSP on YouTube. From what I can tell all the graphics are correct! I don't notice any problem at all with the billboards they look perfect. The only problems are the aforementioned fmvs backgrounds and I've noticed the nitro effect is a little heavy.... It has a slight stutter at the beginning and at the end and I have all my CPU cores maxed out on my phone and GPU set to 499Mhz (SD 855+). I don't know if that can be optimized or not. Also the lens flare is still green on opengl.

Now that #16461 is in, closing.
