FPS drops to 0-10 when I hover the mouse over the window after the game switched to UE5

If the window is just active but the mouse isn't over it, the FPS doesn't drop - I can walk around with normal FPS, but as soon as I move the mouse over the window, it drops to 0-10. - All drivers are updated to the latest versions. - No additional mouse software is installed. - RawInput buffer in the game settings doesn't help. - Windowed, Fullscreen, and Borderless modes don't make a difference. Specs: R5 5600X / RX 6750 XT / 32 GiB / 1k mouse polling rate / Win11 24h2

does it happen in the main menu

It happens everywhere. FPS is fine when the window is active but mouse isn't over it - i can move/chat normally. The moment mouse enters the window, FPS instantly drops. I found the solution! I was using RBTray to minimize any application to the tray with the Ctrl+Alt+Down_Arrow hotkey. For some reason, this program was conflicting with the game.
