No flickering for six days, after compiling a newer kernel, because Manjaro takes forever to release a new Kernel, even if the current one is broken.
Looks like it's three versions behind, I'm to lazy to compile the newer version. Also, it'll probably result in the flickering being back again.
What's the point in an open source video driver if it flickers? Well, you probably can't use the closed source version with a newer Kernel.
I like how before you could set "amdgpu.dc" to 0 and there'd be no flickering. That doesn't work anymore, set to one works in 4.20.3.
Opening bug reports is for non lazy people.
