This doesn't look like a graphics issue. If anything, it looks like a cursor offset issue.
Can you try the following:

1. Restart JOSM
2. Update your computer software
3. Restart your computer
4. Try a different desktop environment (like GNOME)

We (JOSM) don't do anything with parsing mouse input for the menu items, so the issue is likely in one of the following locations:

• Java itself
• The OS (possible but unlikely)
• The hardware (unlikely)

Also, your version of JOSM is out of date. The current release is r19230.

Another person confirmed that he also has this error with different DE, so i assumed it is related with soft itself, since it is only program with such visual problems.

When the window is maximized or its size is changed at all, I can't use the menu (File, Edit, etc.). If I hold the left mouse button down, I can see the items in that menu, but releasing the mouse button makes the drop-down menu go away. Clicking on the menu just makes the drop-down quickly appear and disappear. When the window is left at its default size when JOSM launches, the issue does not occur. Never seen this happen with any other application, very odd. I'm also on KDE Plasma, with JOSM installed via Flatpak.

[taylor.smock]

My home machine is Fedora Silverblue (GNOME), and the JOSM flatpak doesn't exhibit that behavior on my machine.

I was able to reproduce in a VM with KDE Plasma (X11 and Wayland). I was unable to reproduce in the same VM using GNOME.

This is most likely a bug in KDE Plasma or Java since (AFAIK) we don't do anything specific to a WM.

Realistically, I'd want go through KDE releases to see which KDE version caused the issue (I suspect KDE over Java).

@Rafal:

As you're using Tumbleweed, my first suggestion would be to upgrade to Java 21, 22 or even 23.

@Taylor:

KDE is really more unstable ATM than normally. I'd also suspect it :-)

Another KDE user here, I have updated to 6.2 and the bug still exists.

[taylor.smock]

As I noted in comment:4, I don't know when the problem was introduced in KDE. I don't use KDE personally.

The KDE developers probably don't know there is a problem, to be honest. I'd open a ticket with them, but I don't know which release actually broke things. I'd guess 6.1 if 6.2 just came out. But I don't know.

Anyway, I tried with a different Java application (IntelliJ PyCharm), and it exhibited the same behavior.

It looks like KDE uses ​bugs.kde.org for their bugtracker.

EDIT: Or if the problem just started occurring, it might be KDE Plasma 6.2 instead of 6.1. It depends upon when the problem was first noticed.

I was having issues on Plasma but some recent updates seem to have fixed it! It's not happening anymore.
