Hello,
First of all, thank you for creating a native Linux version of AIMP.
I've used it for a couple of days and so far found 2 minor issues that weren't present in the Windows version of AIMP that I used to run via Wine.

- The Linux version doesn't display external cover arts (by external, I mean .jpg or .png file placed in the same directory as the audio files). It displays cover arts only if they are embedded into the audio file.

- Also, when third party skins are used, there is a white rectangle around context menus as shown in the following screenshot: (The skin in question is Black Onix Two, originally made for AIMP 4.10)
