1. Programm works slowly, cursor moves much faster than brush, all functions are delayed. My computer is near to recommended system requirements
2. When i open a saved document there is only a blank canvas
3. Some brushes look like this and don't work correctly:


4. Is it a bug or a feature??

5. Lots of warning messages after running, such as "Byte code invalide! Error = r2dPixelShader.Template", "Failed to load image" and many other
Sorry if i made/wrote something wrong
