Custom Visuals become blurry when zooming the canvas

[tarockx]

Hello everyone

I am experiencing a weird problem with all my power bi custom visuals that I am pretty sure only appeared recently.

Basically, whenever I set the report canvas to a zoom level other than 100%, my custom visuals (especially the fonts) become all blurry.

Initially I thought this was normal and that the zoom performed some crappy non-vectorial zoom on the entire canvas, but after further testing I noticed that this is not the case: the Power Bi native visuals are always crisp and clear no matter the zoom level, so it must be some specific issue with custom visuals.

Here is a screenshot to showcase the issue (NOTE: the issue may be less noticeable if you view the image inline, if you download it and zoom in it will be more clear):

As you can see, at 100% zoom level both the native Table and my custom button are cripy and display well.

But at 90% zoom you can see that the native Table is still crispy, while the text inside my button is blurry and almost unreadable.

I already tried to play around with font sizes (using em/rem to make the font size proportional, etc.) but nothing changed.

Is anyone else experiencing this issue? Any way to avoid/fix it?

For the people that are experiencing this issue, an update: I've heard back from Microsoft support and they confirmed the issue is known and under investigation.

Still under investigation, I presume? Very ugly...

The issue has been pushed back from MS to the Chromium team, who are currently working on a fix for all Chromium-based browsers. There is still no ETA 😞

When debugging in chrome, this problem was always there, no one cares about the developer's eyes.

Not for me—I can downgrade Chrome to a recent, but earlier version, and the visuals are clear. However, the blurriness is now happening in Edge for me since I upgraded to the latest version (127.0.2651.86), so this is going to affect more users as they start to update their browsers too 😞

In pbi desktop, imported .pbiviz, in my opinion, does not soap, I'm not sure), I only care during development-debugging), I don't use them.

Hi @tarockx,

Are you using Chrome? If so, this seems to be an issue with the latest version. I haven't observed in Edge yet (and Firefox looks OK to me), but I suspect that as Edge and Desktop are Chromium-based, they will eventually catch up.

I raised this with MS a few weeks ago, and they said they're looking into it, but I recommend you also raise a support issue at pbicvsupport@microsoft.com so they can be aware of the impact on users other than myself.

Regards,

Daniel

Hi All, I am also experiencing this issue with blurry custom visuals for a few weeks now when you view the page at anything but 100% zoom.  I had raised this with one of the custom visual providers and they said that it was caused by an API update from Microsoft a few weeks ago.

I hope this is going to be fixed quickly because it is affecting user experience.
