Hello Factorio team, noted there`s an issue with the lightsync on a Logitech G915 keyboard. I`ve searched around and there was only one other recent mention about it.
The behavior:
When booting the game only the Special keys on the left of the keyboard (the G1 to G5 keys) light up. They also flicker when the keyboard is plugged. No special steps taken to encounter the issue.

The game version is 2.0.77 build 84539 expansion on GOG.
The Logitech GHub app version is 2026.4.919028. (Basically the latest updates.)

It`s an S3 P1 so i hope this gets resolved at one point in the future without reverting back to older GHub versions.

I tried out the G512 keyboard I have for testing and it worked perfectly on ghub version 2025.5.730277 and didn't work at all on the latest version. I tried to update the SDK we're using but there are no updates. So, what ever is broken - is up to logitech to fix as there's nothing code wise we can do on our end. I've started trying to contact them about it to see what happened.

I have the same issue with my G915 also. I had to revert back to a GHUB version where it worked. logitech-g-hub-2025-7-768359 I used ghub 2025 7 768359. and then reupdated to the current version and it works again. I did keep the settings when downgrading and updating too. For some reason just reinstalling the newest version doesn't work.

Hope this helps you as it was driving me CRAZY!!

I contacted Logitech about this issue and they say they have it fixed internally but don't know when it will be released.

jftr: G815 has the same behaviour.

Just to help anyone troubleshooting this like me, light effect is still broken just like the OP descripted after updating to GHUB 2026.5.939708
