UI glitch in debug mode

[gaben]

What steps will reproduce the problem?

1. Prepare JOSM in IntelliJ
2. Debug the JAR file

What is the expected result?

JOSM UI works as usual.

What happens instead?

Weird UI glitches everywhere. See the similar repetitive icons and mixed translations.

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

Java version: 17.0.8.1+1-Ubuntu-0ubuntu122.04, Private Build, OpenJDK 64-Bit Server VM
VM arguments: [-Djosm.cache=<josm.cache>, -Djosm.pref=<josm.pref>, -Djosm.userdata=<josm.userdata>, -agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=127.0.0.1:37241, -Dfile.encoding=UTF-8, -Duser.country=HU, -Duser.language=hu, -Duser.variant]

You have some missing VM arguments. I don't think they should affect anything, but it is a possibility.

It is working for me when I start JOSM from the command line with java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=\*:5005 -jar dist/josm-custom.jar. Note that I'm on macos, not Ubuntu though.

Thanks, I'll check it. I'm using VMware Workstation if it's making a difference, probably shouldn't.

[taylor.smock]

I have no clue. I would assume it is better than Virtualbox, but IDK.

I have seen graphical issues in Virtualbox before, so that might be the problem. But I don't know why it would make a difference. It seems like it is reading the same image file for all three buttons, and I don't know how or why that would happen.

Not just the icons, but the slippy map is affected as well. Maybe it's some caching issue?

[taylor.smock]

Maybe, but I doubt it; the slippy map and icons use two separate paths, and both use different keys for caching. The icons use the icon path ("images/image.svg") while the slippy map uses the tile ("z/x/y"). I'd try a different renderer, but I think Java only has an OpenGL backend for linux.

My best guess is there is some kind of issue with BufferedImage with the driver that the VM uses.

If you have another (spare) machine, I'd try on that machine.

[gaben]

Good idea, thanks for the suggestion. I have multiple VMs and a physically dual bootable system, so technically I can test anything. The rest is just time and experience which I both lack for proper debugging.

Backstory: I develop in a VM and have never run a JOSM development instance on a bare OS.

Solution: disable 3D acceleration for the VM, as suggested in ​https://youtrack.jetbrains.com/issue/JBR-4507/After-upgrading-Ubuntu-to-22.04-LTS-some-GUI-elements-are-not-displayed#focus=Comments-27-6793613.0-0

Probably, some software parts are still missing for Wayland (Ubuntu switched from X.org to W in 21.04).

[taylor.smock]

Java still doesn't support Wayland (see ​Project Wakefield). I'm hoping that desktop portals are in scope for it, but I wouldn't hold my breath on that.
