improvement of the progress bar

[GSoftwareDevelopment]

there are possible situations in which the bar is "broken", and its area is not cleared when it is launched

Yes, the "broken" progress bar issue has been fixed, however...

• needs to be optimized - unnecessarily repeats one step
• sometimes there is a problem with a "pest" appearing at the end of the bar when the song starts from the beginning

Removed visual bug :)
