The Devs Makes Big Mistake On version 5.0.1653 or new

On this version, resident evil 4 wii and gamecube, have erro graphics. I think the big mistake is "OGL/Vulkan Drop Destination alpha pass" here you can see the new change on this version 5.0.1653, it's make graphics error with Vulkan and Opengl on some games, not only RS4. The version I see the better build is 5.0.1650, here I can play without graphics error and so smooth on my Android device.
The Model is One Plus 5 128GB internal and 8GB ram.
Please on next builds, try to fix this issue.

This was dropped to simplify code, drop a silly hack and won't likely be making a comeback unless somebody has a very convincing argument *and* example code for a better implementation.

Sorry that your vendor doesn't support the necessary GL/Vulkan features for our current path.

Sorry that your vendor doesn't support the necessary GL/Vulkan features for our current path but in all honesty, nobody really cares about Android right now.

Understand, Qualcomm every time update Vulkan Drivers for Adreno 540. And on version 5.0.1650 can run without error graphics. The problem begins on version 5.0.1653, some changes here affect the graphics in general. I try to test on my GTX1080 with vulkan, have the same issue. I don't see the error with "less extension", but some argument line makes this issue.

Moved to Android!

Your phone's graphics hardware is good enough to run Dolphin. The drivers are not.

Dropping hacks and making cleaner code is how you get a better emulator, if you don't like it, then go use another emulator.

I like and love Dolphin, I just try to help the devs here to make patch's and fix this issue. Yes my phone have powerfull hardware, The android is Nougat 7.1.1. I hope on future, dolphin can be smooth for our devices Android. You can see by yourself, try to test Resident Evil 4 on new version dolphin, you'll se glitch graphics. On version 5.0.1650 don't have glitch, with vulkan API or Opengl.

Sadly, it's your phone's GPU drivers that are buggy and needs patching, not Dolphin. There's little to nothing we can do about that...

This "hack" was dropped for good reason. While it helped in one case, it hurt in many others, and it was judged to be not worth it to support a platform that cannot play many of the affected games at good performance anyway. Plus the developer effort required to maintain and keep this hack working with other emulator improvements just made the cost/benefit ratio even worse.

I'm sure if a developer pops up with interest to either re-introduce thus hack in a way that is clean, and works with the other improvements made to Dolphin since this was dropped, it would be considered for inclusion again. But at this point, none of the (volunteer!) devs have judged this to be interesting enough to be worth their own personal time to do that. Assuming it's possible to implement the same "hack" around the other improvements to the emulator at all.

It was dropped as this hack was the last usage of dual pass rendering. But IIRC there is a pull request to render this correctly with custom blending Wink

-- The author even claims it works well on PVR devices but not on Snapdragon.

Unfortunately, due to a recent employment change that developer no longer has a device that supports the required extension to test on. That will likely change Soon ™, but that's on hold right now.
