Default The (supposedly) black part of the startup (splash) icon is transparent :-)

See screenshot of the splash icon ion front of the web browser ...

Maybe it only shows up on Linux. If it looks correctly on Windows, then my suspicion is that Windows ignores transparency for splash icons.

What window manager do you use? Can you please provide screenshot of the about dialog of JDownloader.
It looks like you are using old installation, because current launcher no longer has such a start splash screen

Can you check by starting JDownloader.jar manually and not via launcher

I'm using XFCE. And in between, I switched to Arch Linux, so my username Ubuntix is outdated ... :-)

If I start java -jar JDownloader.jar directly, there is no splash at all. This is my launcher file:

Code:
[Desktop Entry]
Type=Application
Name=JDownloader 2
Categories=Network;Application;
Exec=/local/software/JDownloader_2/JDownloader2Update
Icon=/local/software/JDownloader_2/.install4j/JDownloader2.png
Hidden=false
I've just tested starting JDownloader2Update from the command line, and then it shows the splash from my OP. The splash icon with the transparent black part looks different than /local/software/JDownloader_2/.install4j/JDownloader2.png.

Yes, my intallation a few years old, I always used the updater. JDownloader2Update has file date "20. Jan 2014" Here it is:

Code:
#!/bin/sh

# Uncomment the following line to override the JVM search sequence
# INSTALL4J_JAVA_HOME_OVERRIDE=
# Uncomment the following line to add additional VM parameters
# INSTALL4J_ADD_VM_PARAMS=

Reading this script, I identified the transparent icon: .install4j/s_14cflck.png

The about dialog is attached.

What really confuses me there ist that it says "Oracle JDK". My JAVA_HOME is set to /usr/lib/jvm/java-8-openjdk, and I also removed the jre folder from the JD2 install dir and symlinked it to /usr/lib/jvm/java-8-openjdk/jre.

Edit:
As a quick fix, I copied .install4j/JDownloader2.png to .install4j/s_14cflck.png

Thanks for the feedback! You can directly start JDownloader and not the update script
For example:
Exec=java -jar JDownloader.jar >/dev/null 2>/dev/null

So you could fix it yourself by copying the image?

Well ... I'm starting it via the update script on purpose ...
So I can ensure having all updates on every start.

Yes, I could fix it by copying the file.

After that, I've noticed that the updater also shows the partly transparent icon in the "Check for updates" dialog. It's only shown at the beginning, before the transition of the icon from pale to opaque.

You can use -forceupdate as parameter (same as in launcher script)
Exec=java -jar JDownloader.jar -forceupdate>/dev/null 2>/dev/null
