JOSM display is just a mess

[ggranvik@…]

What steps will reproduce the problem?

1. Selecting a menu, or opening a popup box.

What is the expected result?

What happens instead?

Screen, menus and popup boxes are just a mess. I have a screen shot I wanted to attach, but where do I put this??.

Please provide any additional information below. Attach a screenshot if possible.

Have to shut down JOSM and restart. Sometimes it will work fine for a while, at other times everything is messed up as soon as I try to select something in a menu or open a data entering box. How can I attach a screen shot??

Forgot to mention, but I have used JOSM for quite a long time - the problems appeared after recent updates (JOSM / Java).

[stoecker]

That's very likely not a JOSM problem. Recommendation would be to switch to a recent Java version, e.g. 16 or 11 (LTS).

Mmh, I have faced problems on startup with the window geometry which I am able to solve by switching into fullscreen (F11) and back to windowed mode (F11)

Sounds more like a memory issue with not enough memory or using swap/virtual memory. Note, JOSM needs more memory for imagery caching lately.
I get all kinds of artifacts when running out of physical memory.

Thanks for the answers!

• I have updated Java a couple of times since encountering the problem, but that hasn't changed anything.

• I use a desktop PC with 32 GB RAM, so there should be plenty of memory...

• I'll try the F11 trick!

You need to upgrade to java version 11 or 16. A simple update will not work. HiDpi is only support from java version 9 on. Additionally, it might give JOSM more memory automatically as it should be 25% of your physical memory by default.

Ok, thanks. I have been using Oracle's Java, which seems to be in version 8. But after Googling "Java ver 16" I found something called OpenJDK. Is that the one I have to use?

Ok, I tried to find Java 11 or 16 Run Time Environment (JRE), but only found SDK (System Developer Kit) - but I'm not programming in Java, so I guess I don't need that. If I start JOSM without Java installed, it points me to Oracle's JRE download page, which only offers version 8 as far as I can see.

If Java 8 doesn't support my high resolution display, it explains the problem, because I did actually upgade to a hi res display recently! I'll try to search again on the net for JRE 11 or 16, but so far I'm stuck...

It seems since Java 10 JDK and JRE are no longer separate:

OpenJDK:

• ​https://jdk.java.net/16/

Oracle Download Version:

• ​https://www.oracle.com/java/technologies/javase-downloads.html

I'd recommend switching to the OpenJDK variant. It should essentially be the same (some proprietary stuff which nobody uses is missing, but step by step that's also dropped by Oracle).

If you have questions or use the Webstart technology instead of the installed Windows exe, have a look here: ​https://adoptopenjdk.net/migration.html

This only applies for the releases on jdk.java.net

AdoptOpenJDK, Oracle, etc. still provide separate downloads for JDK and JRE.

Ok, thanks, I'll check out the webstart option. I did try to download the whole Java 16 package, but didn't find any install program among the zillion files and folders in the zip file. Tried to follow instructions from a web site and copied the whole folder structure to c:\Java, then setting the path in Windows' environment settings, but JOSM reported no Java JRE found on the computer. Seems there are no JRE to be found anywhere newer than version 8.

Go to ​https://adoptopenjdk.net/releases.html
Select version (Hot Spot is ok), Operating system and architecture.
Download JRE or JDK as .msi installer (not .zip). Both, JRE and JDK will work.
Install.
Hope this will help you.

Thanks a lot - a newer JRE without all the Java programming tools was what I had been looking for! I have removed all the other Java stuff and installed the AdoptOpenJDK runtime now, and it seems to work ok with JOSM! :-)

Ok, I close this ticket then. Please, reopen if you face the problem again.
