It seems to happen on software written on java. For example DBeaver or MySQL Workbench when you run some feature, the emergent window shows with a ghost window background like next image:

I think is an issue related with GTK libraries. It not avoid to use the apps but sometimes can be annoying.

Have someone experimented something similar? How did you fixed it?

  • Yes, I have experienced this glitch while working with DisplayCAL application (see pic). I thought it was this particular application's issue. ![ghost window on DisplayCAL](i.sstatic.net/7cUzW.jpg)

  • Hey I'm pretty sure this is a known bug. If you search on the elementary gala GitHub page you'll see the bug report. However I don't think it's fixed yet.
