I have the same issue, and I am using Budgie and the latest kernel Kernel: 5.10.4-165.current.
Also, I have a similar problem happening with Ubuntu on the same machine but soon as I login into the system.
I am using one monitor (HDMI), however, when I disconnect it and connect my USB-C monitor (ASUS-Zenscreen), the problem disappears for Solus at least.
