Apple 27 inch Thunderbolt Display on new MacBook Pro Max Issues

I recently purchased a MacBook Pro Max. I had an older 27 in Apple Thunderbolt Monitor and got an adapter to use along with an LG 32 in 4K monitor via HDMI.

When I use my laptop with The XeBec travel monitors or just with the LG, my system works great. But it seems that when I connect the apple monitor in while using adobe Premiere everything slows way down. Anyone else experiencing this issue? Any fixes? Is this monitor just too old for the new computer?

MacBook Pro 16″, macOS 13.1

I have the same problem.

It started with Apple's Thunderbolt Display and MacBook Pro (14-inch, 2021).

My bet is that adapter (Thunderbolt->USB-C; original from Apple) cannot handle this display properly.

Refresh rate goes up when I disconnect it and connect the adapter, enable/disable ethernet etc. But after few minutes problem comes back.
