--- Comment #11 from Ruoyao Xi <xry111 at outlook.com> ---
My previous comment seems not correct since I am not a professional display
driver developer :(
But now I've found and fixed the bug:
In intel_crtc_page_flip, we changed crtc->primary->fb, but forgot to change
crtc->primary->state->fb.
The fixing is simple, call drm_atomic_set_fb_for_plane to change
crtc->primary->state->fb, keep it same to crtc->primary->fb.
To administrator: (1) Mark this as FIXED. (2) Fix it in kernel tree.
