Godot version

4.0.stable

System information

Arch Linux KDE Plasma, AMD RX 6650 XT, Vulkan, Wayland

Issue description

There's a noticeable input lag in Viewport refreshing. For example, when looking around or moving objects you can tell that it's 3-5 frames behind. Even at >60fps. Attached a video showing the issue - you can see how the pivot is behind the cursor by a few frames.

Steps to reproduce

1. Open Viewport on Linux (Wayland specific?)
2. Try moving objects, you should feel the significant delay

Same happens here on Gnome with Wayland.

Same here. At first launch no input lag, after some time input lag shows up. Here is my issue:

Btw, it just like there is a screen update issue as well. In the last part of the video after I clicked, i have to shake mouse to update the screen. If I click and not move mouse, it' s never update the UI changes. Yesterday i had black tooltips. When i hover some elements, its tooltips shows as black box but today they work correctly, interesting.
