Leaving the ebkac errors out the required information is on "should i use xrender or gl and why" and "what does vertical synchronisation mean" VSync could have a mention about "tearless but lags a frame" notice once it actually works correctly, but the choice about the backend requires a WP/techbase entry. That cannot be reasonably judged or explained in a GUI - no way. I'm sorry. I apparently had opened the drop-down to view the choices, and the tooltip doesn't display while it's opened. Maybe I could suggest adding a little ? icon next to items with tooltips? I know some programs do that. It might make things more obvious for users who don't use a mouse, too. Personal opionion: that tab is called "Advanced" for a good reason. If you don't know what it means, don't change there anything. I don't think it's possible to explain these stuff in a way that would allow users to properly understand it. E.g. the difference between XRender and OpenGL. If I would describe it properly it would end in something that users would think XRender is the better choice. All I could think of is adding a warning: do not change unless you know what you are doing. Going the GNOME way is no solution as I need that advanced dialog for development ;-) The tooltip on the "qt graphics system" dropdown is actually a pretty good explanation, if it was more noticeable. There's no default for the Qt Graphics System, it just stays on whichever value I last selected. I tried to just revert my settings to default, but couldn't figure out what default was. That's why I started trying to figure out what I wanted. The VSync UI has been reworked for 4.11. |
