Razer Blackwidow v3 keys dont register

I have been experiencing this same issue. I’m pretty certain that it’s  and issue with Synapse 4 because the key’s immediately start working again after I focus the Synapse application. From what I noticed is that it only effects lower case “h” and “c” and possibly “k”. When the issue occurs I can type the uppercase variant’s, of the before mentioned keys, just fine but still get no input when lowercase until I tab out of the game and refocus the Synapse application.

It makes me wonder if this issue could be caused buy “Full-screen Windowed” games/applications because I stumbled into similar Issue while using OBS and an eye tracker where the stream video would bug out the second the game was tabbed back into (Counter-Strike 2). Some other person experienced the same exact issue but in Call Of Duty. So in both of those games, they have quite a few compatible issues caused by their Anti-Cheat systems, it’s been reported to cause issues with programs that capture/hook into the game window (Discord Overlays and OBS Game Capture Sources)

So Idk what’s that all about but... I feel like I'm onto something potentially?

Ignore most of my previous reply. I might’ve found the culprit. On Razer's website under "Open Source Software Notices for Razer Synapse" the software is named "(15) Key Code”. I glanced into the Github repository and saw that they mentioned an issue with key press events and how key presses may behave weirdly, especially with upper and lower case keys. This is caused by using the incorrect library for the “Keypress” events, they clarified that you cannot use the KeyCode library with KeyPress events stating “event.keycode and event.which properties of keypress events correspond to ASCII codes, as opposed to keyboard codes. This means non display characters will not be fired on keypress, lowercase characters come out wrong and it's just confusing.”

Here’s the link to the github issue:
https://github.com/timoxley/keycode/wiki/wtf%3F-keydown,-keyup-vs-keypress

They even provided an example of the issue:

—   —   —   —   —   —   —   —   —   —   —   —   —   —   

Example: pressing the 'a' key

document.addEventListener('keydown', function(e) {
  // e.keyCode is 65
  console.log("Key Down", keycode(e.keyCode)) // => 'a' keycode correctly identifies letter 
})

document.addEventListener('keypress', function(e) {
  // e.keyCode is 97 :/
  console.log("Key Press ", keycode(e.keyCode)) // => 'Numpad 1'?? But we pressed 'a'! 
  // keycode has no idea what it's doing, lol.
})
