### Tested versions

### System information

Godot v4.6.1.stable - Linux Mint 21.3 (Virginia) on X11 - X11 display driver, Multi-window, 2 monitors - Vulkan (Forward+) - dedicated NVIDIA GeForce GT 1030 (nvidia; 570.211.01) - AMD Ryzen 5 2600 Six-Core Processor (12 threads) - 31.27 GiB memory

### Issue description

sometimes editor suddenly starts ignoring keystrokes. This applies to script editor, renaming nodes and typing something into an inspector value. Mousebuttons still work. Only resolution is restart the editor.

### Steps to reproduce

Not exactly reproducable. Seems to happen after some work, propably after renaming a node using F2 key. Unsure though what exactly causes this, because ir just happens during work, sometimes minutes after starting the editor, sometimes after hours.

### Minimal reproduction project (MRP)

happens in project I currently work on which I cannot share
