Hi,
I’m reporting what appears to be a clear software issue with Razer Synapse 4, affecting my Razer BlackWidow V3 Mini HyperSpeed.
❗ Issue:
-
The lowercase "q" key does not work at all in Windows (typing, browser, Discord, etc.)
-
The uppercase "Q" works perfectly
-
The key works normally in-game
-
And most importantly:
-
✅ Everything works perfectly when Synapse is closed
-
❌ The issue appears immediately when Synapse is running
-
🧠 Why this is clearly a Synapse issue:
-
The key itself is functional (confirmed in-game and without Synapse)
-
The issue is fully reproducible depending on Synapse state
-
Restarting Synapse temporarily fixes it → then it breaks again
-
No hardware fault possible here
This strongly suggests that Synapse is:
-
overriding input incorrectly
-
or applying a corrupted/hidden mapping to the key
-
or mishandling AZERTY input
🔍 Troubleshooting already done:
-
Clean reboot
-
Synapse restart
-
Key set to default (no macro)
-
Profiles checked and switched
-
Tested different connection modes (USB / 2.4 GHz)
-
Verified AZERTY layout
⚠️ Important detail:
This issue affects only the lowercase input, which is highly unusual and points to:
-
a software-level input handling problem
-
not a hardware or physical key failure
❓ Questions / expectations:
-
Is this a known bug with Synapse 4?
-
Are there known issues with AZERTY layouts?
-
Is there any way to disable Synapse input handling per key?
At this point, the only reliable workaround is closing Synapse entirely, which defeats the purpose of the software.
💻 Setup:
-
Windows 11
-
Synapse 4 (latest version)
-
AZERTY layout
-
BlackWidow V3 Mini HyperSpeed
Thanks for looking into this. This should definitely be investigated as a software bug.
