Windows 11 CS2 random keyboard input bug — keys get stuck after being released

Hi! I have a strange keyboard issue in CS2 on Windows.

Sometimes I press W/A/S/D, release it, but the game still thinks I'm holding the key. Sometimes multiple keys get stuck, e.g. S + D. Pressing the key again sometimes fixes it.

The weird part is that my keyboard tester also shows D=DOWN even after I release the key, and this can sometimes happen outside CS2.

Hardware:

  • Intel Core i5-1135G7
  • Intel Iris Xe
  • 16 GB RAM
  • Cheap Chinese USB keyboard + laptop's built-in keyboard
  • Razer DeathAdder Essential mouse
  • Windows 11 Pro, build 26200
  • Dual boot with Bazzite Linux

The problem never happens in Linux, only Windows.

I've already tried reinstalling keyboard drivers, disabling Razer software/services, testing both keyboards, and testing outside CS2.

Could this be a Windows HID/input issue or a missing KeyUp event? Has anyone experienced something similar?
