Different monospace fonts in different environments

[sitadrost]

I'm using Spyder under Mamba, on Ubuntu 24.04, and have different environments. This week I updated to Spyder 6.0.4 in two of these environments, and noticed that the font had changed in one of them (see screenshots below). As far as I can see under Tools - Preferences - Appearance, both versions use Ubuntu Mono 11 pt, and both have the box "Use the system default interface font" checked. The only difference I've found so far is that in one environment I'm using Python 3.12.8 (top screenshot), and in the other 3.12.6 (bottom screenshot). I don't know, I wouldn't expect that to make a difference for the font that Spyder uses, but I can't find any obvious other differences either (see also version info below).

Is there any way that I can change the Spyder font in the Python 3.12.8 environment back to the font I have in the Python 3.12.6 environment?

Environment 1 (top screenshot):

• Spyder version: 6.0.4 (conda)
• Python version: 3.12.8 64-bit
• Qt version: 5.15.8
• PyQt5 version: 5.15.9
• Operating System: Linux-6.8.0-53-generic-x86_64-with-glibc2.39

Environment 2 (bottom screenshot):

• Spyder version: 6.0.4 (conda)
• Python version: 3.12.6 64-bit
• Qt version: 5.15.8
• PyQt5 version: 5.15.9
• Operating System: Linux-6.8.0-53-generic-x86_64-with-glibc2.39

EDIT: Looking at the screenshots, I noticed that also the IPython versions differ: 8.32.0 vs. 8.27.0. Not sure if that makes a difference.

Hi @sitadrost thank you for the report! Seems like the font size preference is not being applied over your Python 3.12.8 env for the IPython Console? A couple of ideas to check;

• What happens if you change over the preferences the monospace font size preference and apply the changes? Does the IPython Console font size change or it stays the same?

• Could it be possible for you to downgrade IPython in your Python 3.12.8 env from 8.32.0 to 8.27.0?

Let us know if you have new info in order to better understand this after trying the above!

Hi @dalthviz , thanks for your response!

• Sorry, I forgot to mention that in my original report, but yes, I can change fonts and font sizes just fine; it's just that Ubuntu Mono 11 pt looks different in this version than in all previous versions I've had.
• I've just downgraded IPython from 8.32.0 to 8.27.0, but this didn't have any effect on the fonts used in the GUI.

Is there any further information that I can provide, which might be helpful to understand what's going on?
