Can anyone help me with a problem with Photoshop on Linux (Lutris)

I managed to get Photoshop CS6 installed on Lutris, using the script on their site. The problem is however, that whenever I open a file (doesn't matter if it is jpg, png, psd, etc.) the screen remains black. I can see the picture in the Layer thumbnail, but not in the main work-area. Does anyone know what the problem might be? (Also, sorry if this is the wrong place to ask).
