Razer Synapse Macro Randomly Gets Stuck in Infinite Loop – Massive Issue Since Yesterday

Hi everyone,

I would like to report a serious issue related to the Macro feature in Razer Synapse that seems to have started appearing widely since yesterday.

Issue Description

When using the Macro function, even with extremely simple macros (for example, repeatedly triggering the number key “1”), there is a chance that the macro becomes stuck in an infinite loop.

Once this happens:

  • The macro keeps triggering continuously and cannot be stopped

  • Razer Synapse becomes unresponsive

  • The Synapse interface cannot be opened

  • The system keeps receiving repeated key inputs endlessly

The only way to recover is to restart the computer.

However, after rebooting, if the macro feature is used again, the issue may occur again randomly.

Impact

This problem is extremely disruptive because:

  • The macro becomes uncontrollable

  • Synapse stops responding completely

  • The system is flooded with continuous key inputs

Scope of the Issue

This does not appear to be an isolated case.

Since yesterday, I have seen many users reporting the same issue across multiple Chinese platforms including:

  • Douyin

  • Xiaohongshu

  • Bilibili

There are a large number of reports, and many users confirm that:

  • The issue happens immediately after using macros

  • It affects both Razer mous and keyboards

  • It occurs across different device models

This suggests it may be a widespread Synapse bug rather than a hardware issue.

Possible Cause

I am not sure whether this might be related to:

  • A recent Synapse update

  • A background / gradual rollout (gray update)

  • A change in the macro engine

But the timing strongly suggests something changed recently.

Summary

  • Macro may become stuck in an infinite trigger loop

  • Synapse becomes unresponsive

  • Only rebooting the computer can recover

  • Issue started appearing widely since yesterday

  • Occurs across multiple devices and users

I hope the Razer team can investigate this issue as soon as possible, as it appears to be affecting a large number of users.

Thanks.
