Graphical Artifacts Throught The Application (Dell Vostro + nVidia Graphics)

[zchoy@…]

When I launch JOSM using the JNLP link, I get a lot of graphical artifacts. I've attached a screenshot showing one of them.

The status report is also attached.

My computer's configuration is as follows:

• Windows 8 Pro
• Dell Vostro 3460
• Intel Core i7
• 8 GB RAM
• NVidia GeForce GT 630M graphics

We need more info:

• does it only happen with Web Start? What happens with java -jar josm-tested.jar ?
• Have you tried to update your graphics drivers?
• can you try with Java 7 ?
• what happens with older versions of JOSM ? (for example version 7000 in download).
• your status bar looks to be displayed at the top of the screen, does the problem also occurs if you move it at the bottom?

Likely to be a Java bug, I have spotted a few of them: ​8020415, ​8020415, ​6873928, ​6745684

josm-tested.jar?

Still happens

update graphics drivers?

I'm running the latest versions of the Intel and NVidia drivers available from Dell (​http://www.dell.com/support/home/us/en/04/product-support/servicetag/B4Z61W1/drivers).

Java 7

It would be pretty inconvenient for me to try that; let me know if you'd still like me to give that a shot in light of your later post about Java bugs.

older versions (7000)?

Still happens

move taskbar to bottom

Still happens

Java bug 8020415 looks a lot like the problem I'm having.

ok thanks for the answers. No need to do further tests as it show it's not a JOSM problem but a bad combination of Java and graphics drivers. The only option I see is to look at new drivers and new versions of Java frequently, until this bug disappears. Java 8u11 has been released previous week, and 8u20 is planned for August.
