I just installed the Wolfram Desktop 12.1 clean install on windows by first completely uninstalling all previous versions so previous settings don't impact the new installation.

The new front end for version 12.1 is all over the place. Its font sizes are completely ridiculous. At first, I thought bigger fonts can be managed but they are impacting all around.

Suggestion and command templates have smaller font sizes than the rest of the system. Also I can't even see all the columns of the dataset by scrolling all the way to the right (probably because of the extra rounding box around the dataset and huge font sizes).

Another issue found, weird controller placement in Manipulate (By default the ControlPlacement is set to Automatic, so the font changes are probably causing the Automatic algorithm to choose Left as the appropriate default):

Another issue found, WordCloud again based on the Automatic algorithm is causing overlaps since it is not tuned to consider the font changes in 12.1. (By the way, I have SetOptions[$FrontEnd,Magnification->72/96])

  • $\begingroup$ This is an extension of my questions here:mathematica.stackexchange.com/questions/216779/… and here: mathematica.stackexchange.com/questions/217224/… These issues are due to the fact that Wolfram has fixed its decades-old problem with incorrect scaling of notebooks in Windows, but it failed to fix their style sheets and internal definitions of font sizes to match the new rendering. Give it another 20 years or so and they'll get it right, maybe… $\endgroup$

  • $\begingroup$ Or, we could try simply replacing all of the built-in stylesheets in our Windows installation with the ones from the MacOS version, which uses reasonable font sizes. Not that this isn't something that would have been oh so much easier for Wolfram to do in the first place… $\endgroup$

  • $\begingroup$ @Pirx are you encountering the Manipulate controller placement issue as well? $\endgroup$

  • $\begingroup$ No, I don't see that one. I'm on a QHD screen (high-DPI), which may make a difference. What happens if you use a different StyleSheet (I assume you are using the default one in your example)? $\endgroup$

    $\begingroup$ @vsht, all three platforms share the same stylesheets. On Linux, you can specify a css style for the frontend to use. Try the suggestion here. $\endgroup$
