Original GitHub issue: https://github.com/hrydgard/ppsspp/issues/4199
UPDATE (10-16-2013):
The graphic issue disappears when I...
Option 1.) Disabled Hardware Transform
Option 2.) Enabled Hardware Transform + Vertex Cache
Note: Sometimes this glitch also occurs with their mic(s).
@unknownbrackets commented on GitHub (Oct 15, 2013):
Psychedelic. Isn't it better this way? Kidding.
What's the first build that has this issue, and the last build that doesn't? Also, this doesn't happen on Windows?

@Fei-Lix commented on GitHub (Oct 15, 2013):
only hairs but not the face lol
i havent know when this happens but this does not happen in windows
@unknownbrackets commented on GitHub (Oct 15, 2013):
Do you have the texcoord speed hack enabled?
-[Unknown]
@Fei-Lix commented on GitHub (Oct 15, 2013):
yes i have been enabled it, but i think i tried to disabled it before. wait i'll retest
@hrydgard commented on GitHub (Oct 15, 2013):
What GPU does your android device have? Please always report that so we can possibly find and work around any driver bugs.
@Fei-Lix commented on GitHub (Oct 15, 2013):
@unknownbrackets yes, the graphic issue is still present when disabled
@Fei-Lix commented on GitHub (Oct 15, 2013):
@hrydgard Adreno 220
@bollu commented on GitHub (Oct 15, 2013):
it looks like UV coordinates are being rendered rather than the texture itself. weird.
@danyalziakhan commented on GitHub (Oct 15, 2013):
Maybe you have Hardware Transform turned off and texcoord speed hack enabled? Just a guess though.
@Fei-Lix commented on GitHub (Oct 16, 2013):
@DanyalZia I havent experience this kind of graphic issue since back then with the same settings as now. now many weeks later, I reinstalled a latest build of ppsspp in android and this happens and i dont know when this happens. No, my hardware transform is enabled and yes the texcoord speed hack is enabled but disabling it gives no effect
@Fei-Lix commented on GitHub (Oct 16, 2013):
@hrydgard @unknownbrackets @bollu @DanyalZia
ok, I just found that the graphic issue disappears when I...
Option 1.) Disabled Hardware Transform
Option 2.) Enabled Hardware Transform + Vertex Cache
I always wanted to disabling the Vertex Cache to avoid glitches like Project DIVA character's vertex caching are not synchronized when Vertex Cache is enabled.
@Fei-Lix commented on GitHub (Nov 7, 2013):
hmm this issue is still present from the recent builds.
@unknownbrackets commented on GitHub (Jan 22, 2014):
I'm able to reproduce this using the the TGS demo of Project DIVA extend (NPJH90226) on a Samsung Galaxy S3. Annoyingly, it doesn't happen on Windows.
When it draws the face, it:
Toggling any of the settings while the glitch is happening affects it, as described (glitch only when vertex cache is OFF, but hardware transform is still ON.)

@Fei-Lix commented on GitHub (Jan 22, 2014):
@unknownbrackets hmm interesting, thanks for the details :D
@unknownbrackets commented on GitHub (Jun 27, 2014):
This no longer happens for me in the demo. I think something fixed it.
I'm going to close it because I can't reproduce it anymore, and I could reproduce it in the demo before. But if it is still happening, please comment/reopen.

@Fei-Lix commented on GitHub (Jun 27, 2014):
Unfortunately.. it still happens, tested with the most recent build. I think u can ignore this problem if its not necessary to fix at all. but thanks anyways.
@unknownbrackets commented on GitHub (Jun 27, 2014):
Hmm, how come it doesn't happen in the demo? Can you get it to happen in the demo?
Note that I'm using basically default settings, the only settings I toggled were hardware transform and vertex cache. I tried going into songs and also the initial selection screen, which iirc and per your screenshots had the issue before.

@Fei-Lix commented on GitHub (Jun 29, 2014):
dont have the demo but ill find 1.
I tried all the settings, and yes when toggling Vertex Cache doesnt show the psychedelic bug. actually, my issue was about disabling vertex cache makes the character having psychedelic textures. because I'd like their face movements to look properly unlike enabling vertex cache will cause them to glitch.
@unknownbrackets commented on GitHub (Jun 29, 2014):
If I start the game with vertex cache off and hardware transform on and don't toggle anything, it still doesn't happen.
-[Unknown]
@Fei-Lix commented on GitHub (Jun 29, 2014):
I tried all graphic settings untoggled except HW, untoggled Fastmem and I/O.
but still happens here.
I'm downloading the demo, I'll let u know the results later after I tested it.
@Fei-Lix commented on GitHub (Jun 29, 2014):
aw, it gives the same result :(
Disabled Vertex Cache and HW on
@unknownbrackets commented on GitHub (Jan 21, 2015):
I wonder if the changes to the way we bind vbos and element buffers might have improved this somehow. Does it still happen?
-[Unknown]
@Fei-Lix commented on GitHub (Jan 23, 2015):
It still happens (v0.9.9.1-1585)
Note:
Disabled Vertex Cache while the HW Transform was Enabled

enabling vertex cache not help,only disable hardware transform,but slide-show...
@unknownbrackets commented on GitHub (Jun 9, 2018):
Since the latest updates, does this still happen? Also, if it does and your device supports Vulkan, does it happen there?

@Leopard20 commented on GitHub (Jun 10, 2018):
@hrydgard @unknownbrackets
This was fixed a long time ago. Probably since 1.4. Surprised no one reported it! (plus Vertex cache is off by default now)
Tested both OGL and Vulkan on Android.
So I guess you can go ahead and close it! :)
P.S: My device doesn't have that depth issue we discussed earlier either so maybe again it's driver-specific?
@unknownbrackets commented on GitHub (Jun 10, 2018):
This definitely never happened on all devices, though. It's entirely possible it's a driver bug even...

@hrydgard commented on GitHub (Jun 10, 2018):
Either way, I think it's time to close...
