I got the known problem of Kernel 5.19.12 for Intel APU when connecting some Laptop to any external monitors.
The issue:
The main display starts blinking at boot that depends on text input. So each input per a screen blinking.
Solution:
- Downgrade to 5.19.11 fixes this annoying problem.
Do not push it to the stable branch, there are many laptops with Intel APU.
