I know FB2M is mostly for phones with stable resolutions and screen ratios, but I also use FB2M on Windows 10 and when I drag the windows into different sizes and ratios, the buttons such as play/pause, skipnext and skipprev will also be stretched along with the window especially when the window size is half-way between the default ratios. I understand that some images are meant to be stretched along with the window such as position-marker, but I also think it's possible for development and it would be better to fix this issue and make certain button images stay as they were when the window is resized.

Here's the screenshots of the issue:
