It's very possible Gio has a bug or deficiency that increases the input-to-monitor latency, so I'm interested in seeing your GTK program that shows less delay. -- elias
> so I'm interested in seeing your GTK program that shows less delay. I do not have a custom app that I've coded, but I was talking in general. Any GTK application on my distro elementary OS(Ubuntu derivative) is able to keep up with the cursor. For example drag-n-drop of files in the "Files" app or dragging the divider in split view mode in the text editor "Code" or even color picking using a color picker app.
I take that back. I do see a delay on GTK apps as well. For some reason it wasn't apparent when I first tried. Apologies.
