My operating system is Linux Mint 22.3, and my desktop environment is Cinnamon 6.6.7.
I understand that application for KDE are designed primarily to operate within KDE. However, I believe most would agree that basic compatibility with other common desktop environments should be a design object.
Unfortunately, the application KDE Connect is essentially unusable within my environment, due to dysfunction of the scroll bars.
In some cases, scroll bars are displayed but completely unresponsive to interaction, whereas in other cases, the scroll bars are omitted from display in a pane that is intended to be scrollable.
As an example, I will describe my observations for the main window provided by KDE Connect SMS. The window features two main panes situated side by side. The left-hand pane shows a list of contacts, while the right-hand pane shows the message history for the contact selected in the left-hand pane.
The behavior I observe is that for the right-hand pane, a vertical scroll bar is displayed, but is completely unresponsive to cursor interaction. Worse, no scroll bar is even displayed for the left-hand pane, even as the full contents exceed the physical height of the pane.
I regret that I am not sufficiently knowledgeable to speculate meaningfully whether the dysfunction should be attributed to KDE Connect, to KDE, or to Cinnamon. However, I do appreciate assistance determining a resolution to the lack of usability in my environment.
