I also posted this in another forum but no one answered.
I have a problem using Vsync with games/softwares that use the Vulkan API.
Software like Dolphin,PPSSPP and RetroArch get constant tearing issues that I dont get with other API's like Directx 11 or 12.
I am using a Dell Inspiron 17 5000 series.
It's using the AMD GPU Radeon 530 and the Intel GPU Intel UHD 620.
The OS is Windows 10 and the CPU is Intel i7-8550U.
The developers of Dolphin believe it's a driver problem and not a software one.
Here is the bug on their issue tracker : https://bugs.dolphin-emu.org/issues/11674.
I tried to force vsync from AMD settings and it didnt work as well.
