This looks very similar to an issue already reported in the IBM Planning Analytics community in July 2025:
“Bold Fonts are fuzzy in PAW 105”
https://community.ibm.com/community/user/discussion/bold-fonts-are-fuzzy-in-paw-105
Several users described a very similar pattern: bold text in PAW buttons and text boxes suddenly appeared darker, fuzzy and more rounded. The reports covered different PAW versions, and the behavior was seen across Chromium-based browsers. Arden Miller also opened IBM Support ticket TS019847865 and reported a connection with Windows updates in their environment.
So I would not start by assuming that the dashboards themselves were redesigned or that the IBM Plex font files are necessarily wrong. The books can still request the same Bold weight while the way that weight is rendered on the client changes.
There is also some history of IBM Plex / Chromium / Windows font-weight issues, although the older IBM Plex issue is not necessarily the same defect.
Based on the public information, the interesting points are:
- similar visual change affecting Bold text in PAW text boxes and buttons
- reports across different PAW versions
- reports involving different browsers
- a reported timing relationship with Windows / browser updates
- a concrete IBM Support case: TS019847865
What I have not found publicly is an APAR that maps TS019847865 to a specific PAW, browser, or Windows fix. I therefore would not assume that the dashboards need to be changed.
Before redesigning anything, I would check whether the same book renders differently on another client and, using the browser developer tools, which actual font face is being rendered for the Bold text.
It would be particularly useful if someone from IBM could confirm whether TS019847865 was fixed or worked around in a particular PAW, Chromium/browser, or Windows version. That would help determine whether this is a dashboard configuration issue or primarily a client-side font-rendering issue.
