Recently I noticed a white flash on startup, right after the kernel mounts the root filesystem. I figured that this was caused by my graphics driver (amdgpu driver with RX-480). After I put the amdgpu module in the initcpio, the issue was resolved. However I still wonder what caused it. The flash looks like a regular small grid of all kinds of colors. It's there for a split second.
Other people might experience the same thing, is it possible to include this fix in mhwd? How would I write such a patch myself?
Thank you in advance!
