After resizing the window the UI shows a weird resizing effect with some gui elements. This is with 3.0.4 right now.

You can see for yourself on https://store.steampowered.com/app/709240/Ingnomia/ and the code would be on https://github.com/rschurade/Ingnomia

Let me know if I should open a ticket on the bug tracker or if you need further info.

Could you please try with the latest version (3.0.6) and if the problem persists open a new issue in the tracker?

Still there in 3.0.6, created ticket.

Thanks for the ticket, we'lll investigate it.
