JOSM.exe runs upscaled

[anonymous]

What steps will reproduce the problem?

1. When I run latest Windows 18191 JOSM.exe JOSM is upscaled, when I run .jar using command prompt "java -jar josm-custom.jar" everything is ok.

What is the expected result?

What happens instead?

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

Spotted the issue: Java version: 16.0.2+7 + scaling 1.25×1.25.

Java 8+ fractional scaling on Windows is weird. See my comment here. I guess when you run it with jar, you actually run it with Java 8 where everything* looks good. The whole issue originates around ​JDK-8055212.

*everything: nearly, but sadly no, see eg. #20850

HiDpi support was added in java 9. Please, take a look at the status report when running the .jar file. It should tell you which java version is used.

I think it's fair to assume it is a major usability issue. Users just started using the new exe and already having issues.

[InsertUser]

I am also getting a comically enlarged version of JOSM after the latest update to 18193. The file menu now scrolls because it won't fit on the screen. Map tiles also appear to be rendering too small. Unfortunately the 18118 version left behind by the new installer now complains about plugins that it is too old for.

Is there a way to fix this?

[skyper]

Is this a problem with the windows installer or a general issue with hiDPI + Windows + java16?

[Don-vip]

Customized scaling issue, behaviour changed for users who went straight from Java 8 to Java 16 with the new installer:
#21278: 1920×1080 (scaling 1.25×1.25)
#21283: 1920×1080 (scaling 1.25×1.25)
#21297: 3200×1800 (scaling 2.00×2.00)

[Don-vip]

Milestone renamed

[Don-vip]

I tried to increase Windows scaling and I confirm icons are bigger with Java11+... but I think Java 8 behaviour was simply wrong.

[gaben]

Just the icons? For me, it looks the same as in the report.

[Don-vip]

The text is bigger too but is the same for me between Java 8 and Java 11+, and that's the whole point of this Windows setting.

[InsertUser]

I've just played with my windows scaling settings, everything seems to be scaling along with the slider, but unfortunately the icon and text sizes are significantly bigger than the Windows defaults for other apps.

Were these bumped up in size to compensate for the lack of proper scaling before? Is there a setting somewhere to put them back to something reasonable?

[gaben]

Replying to InsertUser:

Yes, scaling was changed in Java 9, see ​JEP 262. You can start inspecting the issue around here ​https://stackoverflow.com/q/47613006.

Hey, have you a workaround for a run-of-the-mill user? For me, this issue is critical, because I can not read some texts, buttons text is somewhere pixelated.....

[skyper]

Did you try it with new, empty preferences?
Did you take a look at the mentioned system settings in the link to stackoverflow above?
Text size may depend on the font you use which can be changed in advanced preferences.

[Don-vip]

I don't see this as a critical issue. I tried the custom scaling and Windows becomes really ugly. JOSM becomes ugly as well with bigger icons but at least it's consistent with the system. I will accept patches if someone want to dig into this but I will focus my time on more important issues.

[Don-vip]

The workaround is to revert Windows scaling settings and stick to 100%.

[InsertUser]

Don-vip:

This is not an acceptable workaround. Other apps that observe proper scaling then become too small to use comfortably. Making the rest of the system less usable because of a JOSM specific issue is not a solution.

Don-vip:

It is not consistent as it appear that JOSM text and icon sizes are artificially enlarged compared to other apps even without any scaling.

[gaben]

If you do it right, only badly behaving Java apps will be ugly, not limited to JOSM. A good example would be JetBrains IDEs with consistent look, although they use their own JRE.

I think there is a reason why anyone uses other than 100% scaling, so better workaround to stick to Java 8 with .jnlp or .jar until it's fixed.

Same problem. Nothing changed.

I don't have changed there anything. Wich key would be changed?

Replying to Don-vip:

I see there a critical issue, when JOSM is not workable. I have added some screenshots. See yourself.
Scaling 100%, FullHD (1920x1080px). Before the update JOSM were around 2x or 3x smaller....

Replying to Don-vip:

The workaround is to revert Windows scaling settings and stick to 100%.

As I wrote further: My Screen, where I use JOSM is on scaling 100%. lower is not possible.
I don't see any workaround here...?

[Don-vip]

@SafetyIng can you please post your status report? All bug reports I saw on this subject had a custom scaling from 1.25 to 2.00.

[InsertUser]

After a brief test it seems that setting the program compatibility mode to put all of the scaling onto the application brings the text size on the menus to a text sizes seem more consistent with the rest of the OS and in line with my install of LibreOffice 7.2. The icons are still seem a bit big, but that seems to be happening with LibreOffice too so I'm probably just a bit too used to the previous version's mini-icons. With this set the file menu items now all fit on screen without an arrow for the overflow. With this set JOSM does still change scale along with the global Windows setting.

Settings accessed via: Right click on JOSM in taskbar > Right click on JOSM > 🔧 Properties > Compatibility > Change high DPI settings > ☑ Override high DPI scaling behaviour. Scaling performed by: Application

NB my default scale is 150% so won't help with anyone who finds things too big at 100%.

I use JOSM on my display1 - interesting is, that there a scaling of 1.25x1.25 is listed, but in my computer settings there is set up 100% (1.00x1.00) so something must go wrong in the Setup of JOSM <-> Java <-> OS...?

Interesting, speaking of hardware, what is your screen monitor (manufacturer/model)? Is 1920×1080 the native resolution?

Somewhere the scaling must be set. Either in Windows general, as general option for java or in the startup script.
Sorry, I have not Windows so all I can do is reading.
I guess somewhere -Dsun.java2d.uiScale=* or -Dprism.allowhidpi=* is set or missing.

Text size may depend on the font you use which can be changed in advanced preferences.

I don't have changed there anything. Wich key would be changed?

I hope we find the setting causing this in first place but last option are font and icon size. Just search for font resp. iconsize in advanced preferences. (You need to enable expert mode for it.)

I use a DELL P2217 ; and yes 1920x1080 is native.

Then i would say, it miss in the windows starter`?

I found a fontsize with the entry 8, the normal iconsizes were between 16 and 24 (i think pixel?) For me, the reality is a little bit too big for 16 or 24px....

[SafetyIng]

Hey, I think this fits here. When I have JOSM on my screen 1 for a longer time and i move it to the screen 2 then it is scaled some crazy things, i can't describe. So I added a screenshot as an attachment.

[anonymous]

what is the main problem, when for some it works normally? so how can I solve this problem when I use 1920x1080 resolution and 125% scale in windows? I'm fine with this, but it's not good in josm

[Multi Pass]

Here's a workaround that may help someone:

I run "java -jar josm-custom.jar" to launch JOSM using Windows with system scaling at 150%.

Normally I scale JOSM back to 100% through JOSM in taskbar > Right click on JOSM > 🔧 Properties > Compatibility > Change high DPI settings > ☑ Override high DPI scaling behaviour. Scaling performed by: Application

I upgraded to Zulu JRE 17 after seeing the message "JOSM soon will no longer support this version of Java, you should update to version 11 or better"

However, the new version of Java does not respect the application scaling setting as stated above.

Scaling is fixed if JOSM is launched with -Dsun.java2d.uiScale=1.0 ("java -Dsun.java2d.uiScale=1.0 -jar josm-custom.jar"), high dpi settings are default (unchecked).

SUMMARY
For JRE 11+ -Dsun.java2d.uiScale=1.0 has the same 100% scaling effect as Right click > Properties > Compatibility > Change high DPI settings for JRE 8.

[Klerik7]

could someone show me on the screen where exactly I can find this setting to change the DPI? I can't find it

Would be nice, if you could document your findings under Help/HiDPISupport, thanks.
