I would certainly like to try to fix this, but so far I'm not sure what is exactly happening and why. It's the first time I'm hearing about this bug.
Could you perhaps send me a screenshot of the bug and maybe some details about your operating system, graphics card, graphics drivers and such. You can e-mail them to me at support at lezliz.com.
Thank you for letting me know about this, and sorry for the inconvenience!
