Hi,

When I run Dolphin-5.0 on my linux system with openbox and jwm -- it shows black images in place of game banners, region flags and state stars.

Strangely, but my other system (with openbox and lxde) shows it all perfectly.

It seems that banners (banner.bin) are not "normal" images, but some binaries of unknown format. Maybe they need some special lib for support?

I tried to fugure out what's wrong here, but couldn't find anything...

That sounds strange. Region flags and state stars are just PNGs. Banners aren't in a standard format, but Dolphin contains all the code needed for decoding them. (Exception: The banner of Wii games that don't have save files are a PNG file.)

Found it -- it was display depth...
The system with black banners has a 10-bit display (i.e. "Default depth 30" in xorg.conf).
If set to 24 bit -- the banners, flags and stars are normal.
Not sure who's responsible for handling PNGs on a 10-bit display, but if it's Dolphin -- it would be great to make it work with 10 bit.

UPD. After some more tests: everything is Ok with images at 30-bit display and QT5 GUI. Unfortunately, otherwise QT GUI is unusable.
The problem of black images at 30-bit display is somewhere in wxWidgets GUI.
