Created attachment 130982 [details] UI SUMMARY Horizontal and vertical scrollbar invisible until mouse is placed over. In dark theme, it's nearly impossible to find it. Breeze theme is okay but only shows when mouse is on top of it. 20.04 worked great! 20.08, not any more. Ubuntu 19.10, Using Appimage.
