I can see where it\'s possible to change editor fonts, but the project panel font seems unreasonably large. Overriding the default fonts only changes the upper path bar and
The fix for me was to switch the Theme from GTK+ to IntelliJ, I confirm that Darcula works as well. The fonts broke for me following a switch to proprietary NVIDIA video drivers. On Manjaro Linux running Android Studio.
I recently had the problem as well; suddenly the font in the project panel was larger than the others. However, I found a hidden option in the settings of IntelliJ which disables this odd behavior:
~\.IdeaIC2018.1\config\options\ide.general.xml
bigger.font.in.project.view
to false
This is what the file now looks like for me:
<application>
<component name="GeneralSettings">
<option name="confirmExit" value="false" />
<option name="processCloseConfirmation" value="TERMINATE" />
<option name="searchInBackground" value="true" />
</component>
<component name="Registry">
<entry key="ide.tooltip.initialDelay" value="604" />
<entry key="tabs.alphabetical" value="true" />
<entry key="SBT.system.in.process" value="true" />
<entry key="bigger.font.in.project.view" value="false" />
</component>
</application>
I did not found this option in the GUI though.
there is another settings for the UI elemens in Settings->Appearance->Override default fonts checkbox.
