#16076 reopened defect

Second dialog window underneath the first window on macOS

Reported by: nkamapper Owned by: team
Priority: normal Milestone:
Component: Core Version:
Keywords: template_report macos javabug Cc:


What steps will reproduce the problem?

Whenever a second popup/dialogue window appears, it is displayed underneath the first dialogue window.
1) First open Imagery Preferences window, then hit the TMS, WMS etc buttons to display the second dialogue window.
2) First open Download from Overpass API, then hit the Query Wiard button.

When I click on the top window (i.e. the first window) within the boundaries of the second window, the second window is displayed properly.

I run JOSM on MacOS. Same behavior on 4 Macs. This problem appeared approx. a year ago.

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

This problem appeared approx. a year ago.

Just a general note: it's easier to fix problems when they are reported as soon as they're detected :)

Naive assumption: If I wait long enough, the problem will go away ... :)

comment:3 by nkamapper, 6 years ago

I still have this problem. Cannot see popup windows including error messages because they appear behind the first window.

Never seen that on Windows and don't have any similar report on Linux, so probably macOS specific.

comment:5 by Don-vip, 6 years ago

macOS bug reports never go away by themselves for a simple reason: none of us own a mac. If you know Java developers with a mac, tell them to contribute to JOSM :)

comment:6 by nkamapper, 6 years ago

I updated to Java 10 now and the problem disappeared :)

After one week, this problem is now back on one of the Macs ...
Not sure how that happened,

I think this might be a duplicate of #17849

Can you try the most recent pre-release at ​ and see if you can still reproduce this?

comment:12 by nkamapper, 4 years ago

I tried v17201 but same problem. This has been standard JOSM behavior on all my Macs for the past 3+ years ...
Java 8/261. MacOS 10.15.7.

After v17084 I have had two occasions where a pop-up window is just stuck/will not close (last with the split way function). JOSM continues to have normal operation underneath. Unfortunately I have been unable to reproduce the problem.

Reporter of the other ticket here (I've listed a few specific problem scenarios there).
I sometimes observe a bit different problem, where JOSM loses keyboard input capabilities.
Text input fields cannot be selected, "esc" does not work to close dialogs. Dialogs can be operated and closed with mouse.
In some cases, I tracked this down to some popup dialog being obscured by another dialog, in other cases I've been unable to find out the case.
This seems to mostly happen when system is under high load.

I might have reported this as a separate ticket, but cannot find one right now.

Mentioning it here, as the underlying cause might in the end turn out to be the same.

comment:14 by anonymous, 4 years ago

This issue is still exists for me.

JOSM v17084, macOS Catalina 10.15.7, Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

This happens when calling any modal dialogue when the current input language is not English (in my case, when my input language is Ukrainian). It also creates two layers of data, when you use ⌘+N.

All this happens when you use hotkeys, pressing icons and performing actions through menu items works as expected.
