Comment(by dsd):

 But geode also doesn't affect it. Running new geode on F11 or old geode on
 F14 still results in the bug appearing on F14-only. Possibly something X
 server related.

 However I did determine that the register writes done by geode's
 LXEnterVT() function do fix the problem, even if triggered without a VT
 switch. And I narrowed it down to this exact one:
 {{{
         WRITE_VID32(DF_DISPLAY_CONFIG, 0x29000f);
 }}}

 It's no surprise that the kernels "sledgehammer" register restore approach
 is failing, even if it did take a long time. Various comments in the cim
 code in the geode driver indicate that its important to modify certain
 registers with certain functionalities disabled, etc. another call for a
 KMS driver...

 next experiment: restore that register after the sledgehammer restore at
 the kernel level
