screenshot of display setting

hello,

i have issue related to display settings : the screen goes black when all these
conditions are met :

state = after booting (SDDM is fine, but after that, only black) or after
display goes sleep (after idle for several minutes)
scale = below 100% (see attached screenshot, if scale = 100%, then issue
doesn't occurr)
kernel = 6.5 (in 6.4, issue doesn't occurr)
DE = wayland (in X11, i can't set the scale to below 100%)

when issue occurs, laptop can still receive keyboard instruction (i can send
ctrl+alt+t then input "shutdown now" to turn off laptop) just display doesn't
show anything

i need to set below 100%, because some apps are misbehaving in 1366x768
resolution (that's max resolution on my laptop)

hardaware spec = AMD A9-9420 with discrete GPU radeon 530
