Hi,
I have problems with my Intel UHD Graphics with Intel Core i7-11800H.
After months of digging, through driver settings, trying different versions etc., I have found the main culprit of my laptop's wake issues. When adaptive-sync is enabled, the screen glitches and does not respond when you try to wake from sleep/hibernation. I have found a workaround, simply by writing some scripts to change to monitor refresh rate to a value such that adaptive-sync is disabled at that refresh rate. It is 60 Hz for my monitor, and 165 Hz is where adaptive-sync is enabled. The PC goes to sleep and wakes up perfectly. Then I wrote a script to change back to 165 Hz, but the screen started to glitch again. This time, the screen responds to my inputs and shows the image, but there are horizontal glitches which make it unusable unless I restart the Intel Graphics Driver (ctrl+shift+win+b combination does not fix the glitches, only disabling and re-enabling the intel gpu fix the screen). These horizontal glitches only occur AFTER the PC wakes from sleep (with 60 Hz) AND I change to 165 Hz.
Intel Graphics Drivers with WDDM 2.7 does not have this problem, though they have terrible adaptive-sync performance and many micro-stutters occur when using a WDDM 2.7 driver (which my laptop was shipped with).
I have reached out to my OEM provider and they said there's neither an Intel Graphics Driver, nor a BIOS driver that is newer than mine. So they can not fix this. They offered me to bring my laptop to their service, but I suspect they're going to do anything besides reverting my Intel graphics driver to WDDM 2.7.
Is it possible to fix this? I don't want to restart my graphics driver every time the PC wakes from sleep, as it crashes any programs that were using the Intel GPU. Please help me, I am really desperate at this point. If there are no complete fixes, I would be more than happy for a workaround that is less destructive than restarting the GPU drivers.
Thanks in advance.
