[toigopaul@…]

What steps will reproduce the problem?

1. File -> Open

What is the expected result?

The font size remain constant

What happens instead?

The font approximately doubles in size in both the child open window and the menu bar.

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

File -> Open

This might be a java bug. I don't believe we do any scaling ourselves in the UI, just in the map view.

See also #21278 and #21776.

Does the program compatibility mode as mentioned in comment 27 on #21278 help?

Apparently, yes. If I set the Windows scaling to 100%, the dialogue box appears correctly (i.e. the Open and Cancel buttons are visible), but unreadably small, and the menu bar text size doesn't enlarge. Surely this isn't the recommended workaround, right?

[taylor.smock]

If I had a windows machine, I could probably figure out what exactly is happening and why, but I don't. So the only workaround I know of is the one that skyper mentioned.

What you can do is check and see if the Open/Cancel buttons are appropriately scaled from the 100% test. If the icons are 2.5x larger (250%), then scaling is working appropriately for the buttons, in which case something else is going on.

But looking at the images you attached, the F in File is 21px high initially, and then becomes 53px high (2.52x higher, 52.5 is 2.5x, so it looks like it is getting rounded up 0.5px). Can you attach an image with scaling at 100%?

On my machine (Mac), the File menu is 10px high (non-HiDPI monitor) and is 19px high (HiDPI monitor).

JSOM at open with Windows display scale at 100%

[toigopaul@…]

JSOM with FileOpen child with Windows display scale at 100%

[toigopaul@…]

JSOM at open with Windows display scale at 125%

[toigopaul@…]

JSOM with File/Open child with Windows display scale at 125%

[toigopaul@…]

I just added screen shots with JOSM (forgive me for saying JSOM as I've been just getting familiarized with JSON via Python today):
1) at open with Windows display scale at 100%
2) with FileOpen child with Windows display scale at 100%
3) at open with Windows display scale at 125%
4) with File/Open child with Windows display scale at 125%. Even at 125% the Open and Cancel buttons aren't visible or accessible with the mouse.

[taylor.smock]

I still suspect this is a bug either in Java or in Windows -- we are using the native file dialog in those pictures. I'll see if I can put together a minimal example that you can test and I can send to the upstream Java developers.

In the meantime, you can try disabling Use native file choosers in JOSM Preferences -> Display.

[toigopaul@…]

Thank you! That works! (A side benefit of this ticket is learning about Windows scaling. My eyes can tolerate 200%. After I get my "desk" bifocals, I expect I can do 150%.)
