Public bug reported: With Ubuntu Mantic, Linux 6.5 and Radeon 680M low resolution mode on hiDPI laptop displays is broken. The only resolution I can set is 3840x2400. Setting any lower resolution leads to display corruptions.
So at the moment, only one resolution can be used with hiDPI displays. A commit to fix the issue has been released for Kernel 6.5.4 [0]. It would probably be a good idea to backport it to the Ubuntu Mantic Kernel since this is a severe regression/bug.
