@JAHKO If its any help, i see you all the time in the xev server, i can vouch you're a legit player. never have i once seen you "likely aimbotting" hopefully you can prove your legit, best of luck :)!
I am also getting the exact same issue on Debian 12 and have also verified that T6MP works perfectly on the same machine.
I used the same server key on a Windows and it works fine, so this indicates that it is possibly a Linux/Wine issue. However, considering T6 works fine on the exact same machine with Debian 12 makes me even more confused.
I have done extensive troubleshooting and can't see any way forward without support from the Devs.
