After opening my MacBook Pro (m5pro 24gb 2026) i sometimes get a bug where the whole screen is covered in „Rainbow“-Like Color and everything is Hard to read. Changing Display calibration preset fixes it but only for the Moment. Also when working in lightroom classic the brightness sometimes changes drastically even though everything relating to that is disabled.
MacBook Pro 16″, macOS 26.6
An unusual display issue...
