Please run
Get-CimInstance Win32_VideoController | fl Name
In an administrative Powershell and post the results here so we can check if your GPU needs to be added to the blacklist for gpus that struggle with the matrix theme.

Fyi: the GPU blacklisting system got optimized a few days ago and will become available in the next release.

What I think happened is WinUtil detected the NGIDIA GPU and therefore used a ressource demanding UI, but that GPU is not the one used, so the integraded Graphics are way overloaded.

If you are using a PC, you should plug in your Monitor to the GPU, that are usually the horizontal video ports. If you plug it in to the Mainboard (vertical ones) it always uses the Intel UHD Graphics.

A way to fix that issue in general is to change the way WinUtil detects the GPU, I will look into it that weekend if noone already did.

Thanks for looking into this! Here is the output of the above command.

Name : Intel(R) UHD Graphics 630

Name : NVIDIA GeForce GTX 1650

Actually I am on a Dell XPS 7590 laptop which has a single HDMI output, so I assume the system determines automatically which GPU to use based on the application.

All Right, this problem was already fixed in #2178 and will be resolved for you once the new winutil release is published :) so there's nothing more to do
