Matrix visual column width rendering regression in Power BI Service

tt_and - did you get a workable solution to your problem that started at the weekend, or are the matrix column widths still broken? I've started a new post here as I don't believe that it is only me with the problem: (1) Matrix visual column width problem started April 2... - Microsoft Fabric Community

We are experiencing the same issue and have already opened a support ticket.

To be candid, the suggested workaround is not feasible for us, as it would require updating all existing reports.

We would appreciate it if you could either roll back the recent changes or provide a fix as soon as possible.

Thank you.

Hi tt_and, 
Thank you for reaching out to the Microsoft Fabric Community Forum.

Based on your description, this behaviour appears to be related to how Matrix visuals handle column sizing in Power BI Service. As per Microsoft documentation, Matrix columns can automatically adjust their width depending on content and layout settings (such as auto-size or fit-to-width behaviour), which can override previously applied manual resizing especially when a column is resized smaller than its content.

As a workaround, please try disabling Auto-size column width in the Matrix formatting pane and then manually resizing the columns again. Microsoft also notes that fixed column widths are not strictly enforced in all scenarios, so manual adjustments may be impacted by visual layout behaviour.

You can review the following official documentation for more details:
1. Matrix visual format settings: https://learn.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-matrix-visual-format-settings 
2. Create a Matrix visual in Power BI: https://learn.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-matrix-visual 
3. Matrix visual considerations and limitations: https://learn.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-matrix-visual-considerations 

If the issue started recently without any report changes, it may be due to a change in how the service applies these layout behaviours. Reapplying the layout from Power BI Desktop and republishing can also help ensure consistent rendering.

Hope that clarifies. Let us know if you have any doubts regarding this. We will be happy to help.

Thank you for using the Microsoft Fabric Community Forum.

HI tt_and ,

As multiple users seem to be facing similar behavior based on the discussion, please let us know if the @v-kpoloju, shared workaround helps on your end.

If you need any additional details or clarification from our side, please feel free to let us know.

Hi tt_and ,

We haven’t received any update from your side. Please let us know if you need any additional details or clarification.

Thank you.

I’m experiencing the same issue.

A temporary workaround is to go to:

Format visual → Column headers → Options → Auto-size width

Then disable Auto-size width and enable it again. This restores the expected column widths, but the issue returns as soon as the row headers column is manually resized.

The Worst things is that the latest PBI desktop is not algin with this rule. That is it will not look like the same as what you design in desktop after published
