This is a `known issue <https://github.com/godotengine/godot/issues/38219>`__.
There are two workarounds for this:
- Enable **Interface > Editor > Update Continuously** in the Editor Settings. Keep in mind
this will increase power usage and heat/noise emissions, since the editor will
now be rendering constantly, even if nothing has changed on screen. To
alleviate this, you can increase **Low Processor Mode Sleep Usec** to
``33000`` (30 FPS) in the Editor Settings. This value determines the amount of
*microseconds* between frames to render. Higher values will make the editor
feel less reactive, but will help decrease CPU and GPU usage significantly.
- Alternatively, disable variable refresh rate on your monitor or in the graphics driver.
