Kdenlive Tooltips Missing Problem in Linux Mint
With the mouse cursor placed over a button on the toolbar in Kdenlive, a blank box appears instead of a tooltip. This problem occurs in Linux Mint 19.2, but it may also occur in other Linux Mint Versions and other Linux distributions.
The problem appears to be caused by running software designed for the KDE desktop, on a Gnome desktop.
Kdenlive Tooltip Missing Solution
The missing tooltip problem can be fixed in Linux Mint by installing the Gnome color chooser application. This application can then be used to change the tooltip background color to make the tooltip text visible.
Install Gnome Color Chooser
Search for gnome-color-chooser in the Software Manager in Linux Mint and then install it. Alternatively install it from the command line or terminal window with the following commands.
sudo apt install gnome-color-chooser

Why Choose Mid Grey Color to Fix Kdenlive Tooltips Missing Problem
Mid grey was selected because in Kdenlive, the tooltip text seems to be fixed with a white color. In other applications, such as Qt Creator, tooltip text is fixed black. In order to see the tooltips in both applications, a mid grey is used.
The Foreground color setting in Gnome Color Chooser has no effect on the tooltip text color.
