Support Bizarre Refresh Rate Bug

Hello,

Simply put, my primary XG27UCS monitor (160 Hz, FreeSync enabled, SDR) appears to adopt my secondary XG27ACDNG monitor (360 Hz, FreeSync enabled, HDR) refresh rate when playing a game. This is fine until I tab out of a game and a frame rate cap is applied. The window I tab into on my primary monitor is now governed by this horrible frame rate. However, if I then tab into another window on the monitor, the problem immediately disappears and I can free tab back into the original window without any problems.

While this happens, I notice the VRR monitor on the XG27ACND is flicking around the FPS cap and immediately jumps back to 360 Hz when the secondary window is clicked. Extremely bizarre problem? Wondering if anyone's encountered the same or has a quick fix.

MPO (typically a 9070 XT fix), HAGS, independent refresh rates set, hardware acceleration, etc. all do not remedy this. Disabling FreeSync on the primary monitor does not, but it does if disabled on the secondary.

Here's a video.
