Brightness dims after user login upon KB5030310 installation on a PC with AMD Radeon RX550/550Series
Hi everyone, I would like to report an issue after installing KB5030310 (OS Build 22621.2361) available at https://support.microsoft.com/en-au/topic/september-26-2023-kb5030310-os-build-22621-2361-p...
- I found a temporary solution! Just turn on the HDR then set the "SDR content brightness" slider to minimum, turn off HDR and voila, no more need sleep to have normal brightness. I'm now on 23H2 with RX560.

DUUUUUUUUUUDE, that totally worked for me! THANK YOU, THANK YOU, THANK YOU.
Issue happens to me using an LG Ultragear 27GP750-B over a MSI RX 570 OC Armor with official AMD drivers (version 23.11.1) connected using a DisplayPort 1.4 in case it helps Microsoft troubleshoot. Same as the rest, HDR on everything is OK, HDR off dims the screen after Windows login. The mouse pointer, strangely, retains full brightness and contrast making everything even creepier.
By now it's pretty safe to say this happens to people using AMD's RX 500 series.
