Judging by the code the half-state means that the setting is set to default and the default is dynamically determined. Some effects are en/disabled based on GPU features Yes, this is working completely as intended. The UI could be clearer. I don't have immediate ideas on that. Tri-state checkboxes should only be used for tree views to indicate that only some of a parent item's children are checked. In all other circumstances, it is wrong because the meaning of the "half-checked" state is context-specific cannot be communicated to users--which is the exact problem being described here.
Idea: actually check and uncheck it dynamically depending on whether it is supported by your GPU, with a message in the list item indicating this ("This effect has been automatically disabled because may not work properly with with your graphics hardware.")

Created attachment 139406 [details] Screenshot SUMMARY As you can see in the screenshot, some of the effects are in a half-state, though this doesn't make sense as their state is in reality binary. The systems are set up freshly and those settings haven't been changed yet. Toggling results in "half activated" -> "fully activated" -> "off" -> "fully activated" -> ... so kinda repairs it.
