UI elements randomly turning black, visible if the element is hoverable

[NLBRT - tantus4@…]

What steps will reproduce the problem?

1. Run any version of JOSM on Windows 11 (preferably after 18000+)
2. Use any theme/"Look and Feel"
3. Just do anything.

What is the expected result?

All UI elements in an active popup/drop-down goes black. It comes back visible if the element is hoverable. It has about a 2 in 3 chance of occuring.

What happens instead?

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

Can you reproduce without the FlatLaf plugin installed or with a separate LaF (specifically Metal, although the Windows specific LaF might "look" better).

Replying to taylor.smock:

Yep, I'm actually using Nimbus at the moment, and yet it keeps happening. Again, themes aren't relevant, it just keeps happening.

Anyway, I'm providing some additional screenshots in the attachments.

Same error in Nimbus.

Here's the relation editor, again using the Nimbus theme.

I have seen the same quite some time ago on Linux but I forgot how I got rid of it. Maybe it did just vanish after some time and upgrades of my system.

I wasn't able to reproduce with JOSM r19128 (latest tested) on Windows 11. I was using Java 21 though.

With that said, I strongly suspect a graphics driver issue of some kind.

[NLBRT]

Your suspicions are correct. Earlier today, I was opening Blender after a while, only to see the exact same issue occuring with AMD Drivers. I decided to look it up in their forums and there it was. I'm mentioning the steps to fix it below.

For Windows, this fix is straightforward, but will take ~10 minutes:

1. Download and install Display Driver Uninstaller (DDU) from the official mirror => ​https://www.wagnardsoft.com/display-driver-uninstaller-DDU-
2. From the "Device Type" drop-down on the right, select "GPU". DDU will automatically detect the GPU you're using.
3. Click on "Clean and Restart" at the top. This will uninstall the graphics drivers and restart your PC.
4. Reinstall the drivers, preferably using AMD's new Wizard.

This should work on most devices with AMD GPUs without any sort of roadblocks.

WARNING: Create a backup of your PC before using DDU. Although it creates a recovery point by itself, it's ideal to make one yourself just in case.

Hope this helps!
