Unstable VRR when running native Wayland

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

On Gnome 48, when running RetroArch natively through Wayland using the Vulkan driver, VRR is unable to properly sync the refresh rate with the framerate. With Max Swapchain Images set to 2, the framerate of the game drops. When setting it to 3, the framerate reaches the target, but the refresh rate is still unstable. Both happens regardless of whether or not Sync to Exact content is on or off. Forcing Wayland off with WAYLAND_DISPLAY="" retroarch fixes both issues.

Expected behavior

The monitor would properly sync the refresh rate with RetroArch's framerate.

Steps to reproduce the bug

Run RetroArch on Gnome 48, using a VRR monitor with a refresh rate meter or on a monitor prone to VRR flicker, and using Vulkan Wayland.

No source file or test is named; first reproduce the issue on GNOME 48 Wayland with the Vulkan driver, a VRR monitor, and both swapchain-image settings while comparing native Wayland with WAYLAND_DISPLAY="". Done means the game reaches its target framerate and the monitor refresh rate remains synchronized without instability or flicker.
