Black screen (backlight on) on wake from sleep. (Ventura 13.6) #8

Hello everyone, So far, everything is working, I have only changed some small things for iServices which are also working. I have noticed one issue, and that is whenever I wake my laptop from sleep, the backlight is on, but the screen stays black. I have tried some steps to fix this, and so far none of them work. What should I check or change? Thanks.

Hi. You could try different Framebufferpatches: https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/blob/main/Additional_Files/Framebuffer_Patches/UHD620_Framebuffer_Patches.plist
