Screen lagging/freezing when enabling VRR/Adaptive Sync in Sway

Hi, I just got a new laptop, a Tuxedo Infinitybook Pro 15 Gen 10 (Ryzen 365, 300Hz screen), and while configuring Arch Linux with Sway, I noticed that the system becomes very unstable when enabling VRR/Adaptive Sync.

Having the desktop by itself or Foot terminal open is usually not as bad, but the moment I open Firefox, it starts lagging quite a bit, it becomes unusable. And VRRtest seems to freeze completely with the bars not moving at all.

This only happens when I boot the system (and start sway) with Adaptive Sync enabled from the beginning, if I enable it while the session was already started (and just reload Sway's config) it keeps working fine.

With Adaptive Sync disabled that stops happening, but then, I'll have the different issue that at random times the screen will glitch for less than a second (enough to be noticeable), showing it full of random color pixels.

The screen is set at 2560x1600@300Hz, and Adaptive Sync enabled just by adding

output eDP-1 scale 1.5 adaptive_sync on

I have Sway 1.12, mesa 1.26, and Linux 7.2.11

There's a couple videos showing the issue here https://cloud.foxfox.cat/s/ERp6ZcgrAdsTodG
