[PROBLEM] No more display after in-place update

[Nutul]

Hello,

I've already had the same problem after in-place update from 8.3.4 to 8.3.5 and now it's the same from 8.3.5 to 8.3.6 ; the screen stays black and on without displaying anything and never goes to sleep mode. 

I could only fix the problem with a fresh install.

my working config.txt: 

Code:

[cm4]
otg_mode=1

[pi4]
hdmi_force_hotplug:0=1
hdmi_force_hotplug:1=1

[all]
disable_splash=1
disable_overscan=1
hdmi_drive=1
hdmi_blanking=1
hdmi_force_edid_audio=1
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=on
dtoverlay=disable-wifi
#dtoverlay=disable-bt

Did I miss something ?

Thanks,
Romain

Did the update yesterday night, everything is fine. Only thing it always happens, though, it shows the mouse pointer so that I always have to cycle-switch; and occasionally does not remember the OSK was set to on...
But it works normally.
