Please describe your issue in as much detail as possible:

I have three displays connected to my PC - a 4K TV, a 2K monitor and a FullHD monitor. The 2K monitor is the primary display. When I launch the game, the game logo appears on it for a few seconds, but after that game window doesn't open and flickers in a way that reminds me of https://github.com/ValveSoftware/steam-for-linux/issues/10167 - a similar bug with Steam Big Picture mode. Here's a video demonstration: 2023-12-16 18-06-14.webm

Steps for reproducing this issue:

1. Connect three display devices to the PC like this: Where: 1 - 4K@120 Hz TV connected via HDMI 3 - 2K@144 Hz monitor connected via DisplayPort, primary display 2 - FullHD@60 Hz monitor connected via DisplayPort-DVI adapter
2. Have monitors number 2 and 3 on, number 1 TV is off.
3. Launch Dota 2

I get this issue only on the primary monitor. If I run dota2 on secondary display with -sdl_displayindex 1 it works.
