Possibly. My WindowBlinds themes work fine, but I did have a problem with some themes on another computer. Some problems by the GPU, the drivers or both.
I can't remember what the cause of the overflow was. Usually when an "animation frame container" is created, it adds 3, 3, 3, 3 which is the default setting. I think it was that the problems was that I forgot to empty the array first when loading a configuration. I'm sure that I fixed that, though. If I did, the config should work normally.
