Flickering within Applications in MacOS Sonoma

I confirm this bug has not already been reported

[x] I have searched the issues and this bug has not been reported previously

Describe the bug Hello I have encountered a screen flickering in applications when using quickemu (latest version on latest Fedora with Intel CPU and Nvidia GPU). Those applications flicker.

To Reproduce Steps to reproduce the behavior:

Run quickemu with "default arguments" from the installation guide.
Download League of Legends Client, log in and see it flicker

Expected behavior At least the menues should render without problems, performance wise i hope TFT would be playable. The rest of the VM is super responsive though

Quickemu output Run quickemu or quickemu and include the output of the failure below:
