b1441: Custom Next button in Cartwall bug

Archive mAirList 4.x (English)

I use the same custom graphic for ‘next’ in the Playlist Control Bar, and Cartwall Players.

In the Playlist Control Bar, the Next button displays my custom graphic correctly (admittedly it is never greyed out!).

In a Cartwall Player containing a single item (like player 2 below), the greyed-out version has an odd rectangular (?) artefact behind my custom (transparent PNG) Next graphic. In Cartwall Players with a stack (two or more items, like player 1 below), my custom Next button graphic displays correctly.

Screenshot and custom image PNG files are below, as attachments.

No thoughts on this, Torben?

When there is nothing in the stack, the button is disabled. mAirList uses a grayscale version of the image then, which is generated from the colored image on the fly.

I assume that the grayscaling doesn’t work correctly for that particular image, although I cannot tell why. The “previous” button is OK? Perhaps you can open the two images in an image editor like GIMP and compare the background and transparency settings. They must be different.
