Some graphic bugs I've found, latest YabaSanshiro Pro Android
With Vulkan renderer, on the Retroid Pocket 5;
Resident Evil/Bio Hazard: no zombie on the background in the option menu (happens on OpenGL too, and on PC too). The zombie is rendered but not shown, if you disable some layers on the PC version, you can see that it's rendered. Opening menu text is not rendered correctly too on Vulkan.
F1 Challenge: chase camera is broken (works on OpenGL).
Vandal Hearts: no highlighted text in menu (works on OpenGL).
Sega Rally Championship: some glitches when pressing start on the title screen, broken (heavy flickering) zoom to the car when starting a course. (works on OpenGL). OpenGL btw introduces heavy flickering every time a new menu is loaded.
Besides those, the app is very buggy on my device, it closes unexpectedly, and sometimes after exiting a game, all the games in the menu are gone, you have to restart the app. Sometimes saving a state exits a game too. Decathlete, for example, on Vulkan renderer only plays the first time you open it. If you close and reopen it, the game will crash when starting a discipline. You hablve to restart the device to make it work again. That's very strange. I really like the emulator but lately the compatibility worsened in respect to a couple of years ago... If you need some help with testing I am available.
(Strangely, some graphical glitches, hangs, can be corrected by changing the cartridge and disabling internal backup memory expansion. Something wrong with the memory addresses?)
