First, try if you can also observe the issue trying to rotate your character in the login screen. If so, this might save you a lot of time on subsequent attempts.
Yes, the bug also appears on the character selection screen.
Start the game with WINEDEBUG=+cursor /compiled_wineroot/wine /path/to/Gw2.exe -dx9single &> log.txt
Then try to rotate the character/camera a few times and exit the game.
In the attachments is the log.
