Plasma 5.10.0 introduced an issue which breaks existing Plasma themes. The issue was not present in 5.9.5.

The Plasma panel no longer renders, and its svg element appears to be ignored. However its contents do show, and the blur effect is present accordingly.

Attached is a screenshot showing the issue, using my Plasma theme Freeze; The top part shows the panel displaying correctly, while the bottom shows it no longer rendering as the issue was introduced.

The bug can be seen with the themes Freeze and Colorbit. You can get them both from here for testing:

Comment 1 Mircea Kitsune 2017-06-02 17:07:25 UTC

I think I found the issue: Plasma 5.10.0 apparently changes the objects in the panel-background.svg element: Previously you had a set for each direction, such as #west-mini-center... now there's a single group for everything, such as #center.

I understand I need to update my Plasma themes in this case? Is it normal for compatibility to be broken with the old ones however?

I think the "mini" graphics were never officially supported in Plasma 5. Marco?

I see. This might be a problem as it means breaking compatibility with older Plasma themes which are no longer maintained. I already updated mine once this breakage was introduced, so it's no longer an issue in their case.

I believe this can be closed: I understand this was a deliberate decision as the old svg format for panels is no longer supported. I've already adapted my themes to reflect the change and everything works fine now.
