Microsoft just released an update that fix this issue:

July 31, 2020—KB4568831 (OS Build 19041.423)
https://support.microsoft.com/en-us/help...-kb4568831

Is there someone from Microsoft reading this forum? 

Tested with single monitor and multi-monitor and no flickers anymore even with previous Kodi HDR versions (without workaround).

The update must appear as optional in Windows Update but it can also be downloaded here:

I'm having this problem too. But I'm using both 2 pc monitors and I'm running KODI at 144 hz. Might as well try the 60 Hz if it works. Does changing to 60 Hz I can still play at 4k movies?

Should not be an issue, another possible choice would be a 120hz as a multiple of the movie format, but most of my experience is with 60 cycles.

Same. Tried everything... Nothing works. 

Since Kodi 19, so a few years now, screen flickering during alt+tab... Now on Kodi 21, this still happening. Nvidia card. Tried different drivers and etc. I dont use any external monitors, no wires connected etc. 

Tried to install win update KB4568831, but wasnt able to - although I assume it doesnt matter, when I have no new updates, Im up to date with all recent ones... You can see on reddit people still have same problem, NO SOLUTION yet... 

Someone said: 'I recompiled Kodi to use DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL instead of DXGI_SWAP_EFFECT_FLIP_DISCARD and it worked'..

I have no idea how to do it. Googled - nothing. I couldnt even find DeviceResources.cpp file anywhere. 

I understand that no one has a duty to help anyone and tech savy people think stupid people should suffer, but maybe someone still will be able to help??
