Black screen on menu of Burnout Legends S7Edge Exnyos

[c0manche]

What happens?

Screen is black on startup of Burnout legends using vulkan renderer (renders fine using opengl back end).

Bug first appeared in 1.5.3 was fine in 1.5.2 same bug is pressent in the new 1.5.4

What should happen?

VIdeo should play with menus overlayed

What hardware and operating system are you running PPSSPP on? GPU might matter if it's a graphical issue.

Samsung Galaxy S7Edge (SM-G935F) Exnyos version Mali-T880 vulkan driver version 212.131.1927

So that would implicate:
v1.5.2...v1.5.3

Not seeing anything specific, though...

This happens even with default settings, right (slow effects enabled, buffered rendering enabled)?

[c0manche]

Yes with settings at default buffered rendering slow effects are enabled etc.

was working fine in in all versions going back from 1.5.2 to before in the experimental Vulkan supporting 1.4 series bug first appeared for me in 1.5.3

Strangely Burnout Dominator (same developer) does not exhibit this bug.

reinstalled v1.5.1-12-gc0d0decab (last build before 1.5.2) and it works fine with Burnout Legends

Can you try git builds after 1.5.2 but before 1.5.3?

Was working in the version 1.5.2-49. Bug first appeared in 1.5.3

[unknownbrackets]

That's strange. There weren't really any code changes in v1.5.3 that weren't in v1.5.2-49-g734d9c494. Only two differences: two language files were updated, and the version numbers were updated.

I tried downloading 1.5.3 to test one more time but i can't, the page keep giving me a error. So i downloaded 1.5.3-7, and it's working perfectly. So i started downloading every build after that. Till 1.5.3-50 was working perfectly. 1.5.3-52, there you have it. the bug.

1.5.3-51 " Disable "Accurate Depth" in Burnout games, they have trouble with it on Mali (Z-fighting...) "

Could be related to this?

[hrydgard]

Oh yeah, that'll be it. Older Mali drivers have problems without Accurate Depth, but the setting causes other glitches on the S8 generation of Mali GPUs so I turned it off. Sigh. That one's been reported to ARM for investigation. I guess it'll have to be a driver version check then...

Can you get me the full driver version, that is the hex string after the three numbers in tools/system info? I could calculate it myself I guess but too lazy :)

[hrydgard]

@c0manche please report the Vulkan driver version of your device so I can get the check right. Can be found in settings/tools/system information in PPSSPP.

[VictorRosaB]

Device Galaxy A5 2017, mali t830mp3 exynos 7880.
Api Vulkan, Driver version: 428.43.2674 (6b32ba72)
That will be it?

[hrydgard]

Yup, that's it, thanks! Seems it was broken for longer than I thought. It's fixed in 482.381.3347 on my device so it doesn't happen there. Unless of course it's a hardware dependent bug like the other one... Anyway I'll change the check to match your device.

[c0manche]

Sure

Device Galaxy S7 Edge SM-G935F Mali T-880
