i have been having this problem of screen flickering randomly since i created my project and sometime it stops but then starts again i try tweaking around setting reinstalling hdrp and even try to make a new bland hdrp project but it still does it as soon as i open it i have a hdrp project on 2022 lts version and works fine all the other discussion are related global volume or nan but i have issues even in blank project my gpu is rx6700xt with all the drivers updated
Edit i found the issue you just need to change Graphic Api to direct x11 if it is directx12
go to edit > preffrence > player > graphic api for windows(or your platfrom) there you will see two option in a list one direct3d11 and direct3d 12 drag the direct3d11 to the top and you are good to go hope this helps someone
