Hi @Joulinar! Mind me and i hope this is right thread for this problem.
I’m having issue with my 7 inch waveshare touch display hdmi-c using raspberry pi 4 8gb ram.
Latest os.
During boot up it appear red screen all over the screen. And also red line at the edge of the screen.
I am using dietpi latest version and running lms, squeezelite and chromium-browser.
