Ubuntu Mate下PyCharm字体变细，如何恢复饱满平滑效果？

Hey there, sorry to hear your go-to Inconsolata font in PyCharm suddenly turned thin—total bummer when you’re used to that nice, smooth, readable look. Since you’ve already checked the basic anti-aliasing settings and haven’t modified any configs, let’s dive into some targeted fixes that should bring back that full, smooth appearance:

• Fine-tune the JVM anti-aliasing flag
  Your current -Dawt.useSystemAAFontSettings might be too generic for older PyCharm versions. Try modifying it in the pycharm64.vmoptions file to one of these more specific values:

  • -Dawt.useSystemAAFontSettings=gasp (uses the font's built-in anti-aliasing hints)
  • -Dawt.useSystemAAFontSettings=lcd (optimizes for LCD screens, great for monospace fonts)
    Save the file, then restart PyCharm—this often fixes subtle rendering quirks.

• Refresh PyCharm's font settings
  Sometimes PyCharm glitches and stops respecting system font rendering even if settings look correct. Head to File > Settings > Editor > Font:

  1. Double-check that Inconsolata is still selected as your primary font.
  2. Toggle the "Use system font" checkbox off and back on, then hit "Apply" and restart PyCharm. This forces a refresh of how PyCharm pulls font rendering data from Ubuntu Mate.

• Verify Ubuntu Mate's system font settings
  Even if you didn’t change anything, system updates can quietly tweak font rendering. Open Ubuntu Mate’s Appearance settings, go to the Fonts tab:

  • Make sure anti-aliasing is set to "Subpixel (LCD)" or "Full" (not "None").
  • Adjust the "Hinting" setting—try switching between "Slight" and "Medium" (hinting controls how font edges align with screen pixels, which makes a huge difference for monospace fonts like Inconsolata).

• Clear PyCharm's cached UI data
  Corrupted cache files are a common culprit for weird UI glitches. Go to File > Invalidate Caches / Restart..., select "Invalidate and Restart". This wipes PyCharm’s cached rendering data and often resets fonts to their normal state.

• Reinstall the Inconsolata font
  It’s possible the font files got corrupted somehow (even without you touching them). Uninstall it first via terminal:

  sudo apt remove fonts-inconsolata
  

  Then reinstall it:

  sudo apt install fonts-inconsolata
  

  Restart PyCharm after this to see if the font looks as good as before.
