Hi there, Ben!
Tks for your response. Thing is that as I mentioned in the post - I already tired it all
But I found a solution disabling integrated graphic adapter via BIOS, so everything is running on the discrete GPU. This is not ideal, but it was the only way.
Yeah typically the integrated GPUs on laptops cause issues, the AMD ones especially, and a lot of people miss updating their AMD drivers while focusing on their Nvidia GPU. Glad you found a workaround.
