AE2024 Mercury on and terrible/jagged second monitor output

Hello, another issue with AE2024. Here are my specs:

Prime Z790-P WiFi DDR5 Triple NR 1 M.2 ATX Socket 1700
BEQ043 Pure Loop 360 x Socket Socket NR 1 1700 1200 2066 AM4 AM5
BEQ046 Silent Base 802 Black ATX NR 1
CRA052 RM1000x Shift 1000W PCIe 5.0 NR 1 Modulare 80 Plus Gold
INI768 CORE i9 13900K 3Ghz 24 Core NR 1 Socket LGA1700 no FAN
KIN722 64GB Kit DDR5-5600 Fury Beast NR 2 Black CL40 (2x32GB) 128GB
MIC601 Windows 11 Pro 64bit oem NR 1
PNY223 RTX 4080 16GB VERTO DLSS 3 NR 1 (Latest Studio drivers installed)
SAM885 500GB 980 Pro SSD M.2 NVMe NR 1 Gen 4.0
SAM886 1TB 980 Pro SSD M.2 NVMe Gen NR 1 4.0
SAM903 1TB 990 Pro SSD M.2 NVMe Gen NR 1 4.0

The issue is this: if Mercury (CUDA) is on in project settings, i have a terrible/jugged preview on my second monitor. IT NOT HAPPENS IN PREMIERE.

Here are two grabs with Mercury turned on and off.
