A few symptoms are present in ZynAddSubFX when running from .AppImage.
I'm assigning @lukas-w based on my code review below.
There's a chance we are creating this blank zyn bank bug with the new data:/ syntax. Suspected because .zynaddsubfxXML.cfg shows a line in it that says:
<BANKROOT id="0">
<string name="bank_root">~/banks</string>
</BANKROOT>
<BANKROOT id="1">
<string name="bank_root">./</string>
</BANKROOT>
<BANKROOT id="2">
<string name="bank_root">/usr/share/zynaddsubfx/banks</string>
</BANKROOT>
<BANKROOT id="3">
<string name="bank_root">/usr/local/share/zynaddsubfx/banks</string>
</BANKROOT>
<BANKROOT id="4">
<string name="bank_root">../banks</string>
</BANKROOT>
<BANKROOT id="5">
<string name="bank_root">banks</string>
</BANKROOT>
<BANKROOT id="6">
- <string name="bank_root">data:/presets//ZynAddSubFX</string>
</BANKROOT>
I can confirm that patching ZynAddSubFX helps. Here's my proof of concept code, which I believe fixes a regression from #1719.

The bank selection is still a bit buggy like #1001, but this fixes it so that it works with the checkbox workaround.
