Disabling and re-enabling a monitor causes wrong refresh

[Lownin]

I'm having an issue with frame pacing in games. I sometimes enable and disable monitors because my computer feeds multiple rooms. If I run a game on monitor DP-2, and tell the game to limit to 60FPS, or use vsync, it runs at ~60FPS as expected. If i disable DP-2 with hyprctl keyword monitor "DP-2, disable" and then re-enable it with hyprctl keyword monitor "DP-2, 3440x1440@60, 0x0, 1" then the game appears to run uncapped.

I'm using vkcube to test. VK_INSTANCE_LAYERS=VK_LAYER_MESA_overlay WAYLAND_DEBVUG=1 vkcube sees vkcube running at 120FPS after disabling and re-enabling DP-2. Before disable/re-enable, vkcube runs at 60FPS. vkcube does not have to be running for the issue to occur. I can start vkcube after toggling the monitor, and it still runs at 120. The only way I've found to reset the monitor to 60 is a full reboot.

hyprctl monitors correctly returns DP-2 as being 3440x1440@59.97300 at 0x0. I have vrr is false.

Finally, if I drag vkcube to a monitor that was not disabled and re-enabled, the fame rate returns to the expected 60FPS.

I have some workarounds available to me for taking my monitor out of all my workspace contexts instead of disabling it, but I'd much rather use basic enable/disable commands. Any insights about what's going on here and how to fix it are welcome.

Thanks!
