Oh nice! Thanks for the report :)

I have a ubuntu 20.10 I'll try to reproduce on.

Do you know if this happen consistently, or just once ?

[JorgenPo]

This happens every time I try to press the button

[tbillington]

Going to try bump the rendering library being used (druid) and see if that helps. If it doesn't I don't think there'd be much I can do unfortunately, the issue would be upstream and I haven't been able to replicate it on my computer.

[JorgenPo]

I've tried to compile the app from sources and the file dialog works perfect. The problem only appears on cargo crate

[tbillington]

Okay, I think publishing the current version would fix your issue of installing from crates then. I think the current published version in a bit behind for the UI library (druid).

[tbillington]

@JorgenPo I've published kondo-ui .2 on crates, installing from cargo should work now!

[tbillington]

I'm going to close this since I think it's fixed. Feel free to raise another issue if it persists :)
