I am using JOSM on three computers, all roughly equal configured (laptops with Windows 10, Java 1.8.0 and JOSM 11639).

On only one machine (the oldest), I am able to load and display more than 3 background layers.

On the other two computers, the fourth (and any following) layers will not display in the map until I delete some of the other layers. When one layer has been deleted, the newest layer immediately starts showing its content.

This is not related to visibility of the layers (even with all 3 layers turned "off", the fourth layer will not display), or the order of the layers (the fourth layer can be the top one or the bottom one, no difference).

Is this a configuration setting (something that I have once set on the oldest machine and forgotten to do for the newer ones), or is it a bug in newer releases of JOSM that only shows up on clean installs, or something else?

I've created a JOSM bug report: https://josm.openstreetmap.de/ticket/14593

Works for me (update: with data layers) with a fresh config and 11639 with openJDK JRE 1.8.0 on Linux.

Displaying n layers should work with a fresh install.

Please could you open a bug report (use the link in the JOSM help menu) with one of the machines where it does not work? Adding a screenshot of the JOSM window and a detailed list of which layers and how you add them would be good to have.

Afterwards please mention the bug report link here - for reference of others with the same problem. Thank you!

Thanks, I've created a bug report, and also updated my problem description. (It's specifically connected to background layers. I can have as many data layers as I want.)

@pbb: ah, okay, I have tested with data layers. Screenshots and a detailed description help! Thanks for the good bug report over there. :-)

I wasn't initially aware than the problem only applied to background layers. But you're right, that would have shown up if I had posted screenshots :)

Apparently the problem was me using the 32-bit version of Java. After installing the 64-bit version, I am able to open many more background layers.

I don't really think this is the whole situation, because my guess is that most people only have 32-bit Java installed (since that is the default that the Java website offers), but it doesn't seem other people have the same problem.

But anyway, if this problem turns up, installing 64-bit Java is an easy work-around.
