Welcome to the July 2026 Power BI update! This month, we're introducing new capabilities across reporting, modeling, mobile, and embedded analytics. Highlights include expanded modern visual default...
Thanks alyssaphil , oddly it resolved itself before the team could even raise a ticket! Hoping it was just a severe 'glitch in the matrix' but I guess I'll just have to track it carefully with the next update, likely a QFE before the next monthly release.
DataZoe Appreciate the context, thank you. This really helps in explaining to colleagues why being 'proactive' with the theme file changes is so challenging, and why so often we have to be more 'reactive', though that's obviously less ideal. On the subject of this being in preview though, do you know if this particular slicer issue is expected to be resolved when the 'modern visual defaults...' are made GA?
Edit: A follow-up question if I may, it might be a bug this time but not sure if it's intentional or if something else has changed, but another function which is no longer working is embedding SVG URI's in the theme file for the image visual. It was working previously, but now returns blank.
In the button visual the same function is still working okay, and is a really nice feature to have, but for the image visual it's no longer working for JSON theme file embedded SVG URI's (it still works if the SVG URI is being rendered via DAX measure though). This is unfortunate since the button visual scales everything as a 'square' vs. the container, so any rectangular shaped icons either have 'dead space' around them or are 'scaled down. For example, the following icon (as a button) is actually a rectangular shape, in that it's taller than it is wide. However if I scale the container appropriately, it treats the SVG as a square object, therefore adding dead space like so (zoomed in for clarity):
By contrast, the image visual doesn't suffer from this issue, hence it's preferable for irregular (non-square) button shapes, but unfortunately embedding via the theme file no longer seems to be supported for SVGs?
Edit 2: Sorry, one last update for now, I managed to configure a workaround/solution for the image visual, though it's a bit odd. As per my comment above about embedded SVG's working when derived from data, I did the same thing in the theme file and it seems to finally work again. Screenshot of the code changes below:
With the rest of the code unchanged from before, it now works again like so (also notice how the container now neatly fits around the icon with no dead space):
Please confirm if this is the intended/preferred approach now, or if there's a chance this will also stop working (and I should just stick to the less versatile button visual)? Thanks!
