I am on Ubuntu 18.04 running KDE Plasma, and am running into several issues where the windows are too small and show no content. I have attached a screenshot.
In the screenshot, I was attempting to open the settings for the Device Manager. The same thing happens when trying to open Remote Device Manager.
The only way that I can connect a remote device is by using sdb, which is irritating because the Tizen development tools are heavily based on GUI interaction.
