Graphic bug after screen resolution switching

[StephaneP]

Hi!

Since a long time, I noticed I have some graphic bugs inside Josm.
Repro:

• On Windows 10
• Run Josm on my main laptop screen (1920x1080)
• Connect an external screen with a higher resolution (in my case, 2560x1440) which become the main screen. Josm is displayed on this external LCD.

Then my right panel is sometime empty. I have to undock and dock a panel. (I will to try to take a snapshot the next time I see it).
And I see some vertical tearing and some graphic bugs. these graphic bugs seems located near the old screen periphery.

On the attached video, you can see the vertical tearing and the graphic bug on the city_limit node, "Vieillevigne" is truncated when I move the view.

Sorry, Report added.

[Klumbumbus]

It might be helpful to restart JOSM after the screen resolution changes. You can also try Java 14 instead of Java 8 (if you don't need webstart) if that improves the situation for you.

[StephaneP]

Yes, restarting Josm fix the problem, but that's a workaround.

I'll test with Java 14 later.

[StephaneP]

It's fixed with Java 14. I'll keep it instead of the v8 JRE.
Thank you!
