In the help text for the graphics preferences, there are separate explanations for "Mesh Detail" and "Sky Detail". On the actual preferences panel, there is no settings called "Sky Detail". Instead, "Sky Detail" is called as "Sky" and is a sub-item under the "Mesh Detail". This is confusing. This issue is not new to 1.20 RCs. I believe it is since 1.19.1. I believe this is a bug in the help text, not the preferences panel. We should correct help text to follow the actual panel. I'm not sure the current explanatory text for the "Sky Detail" is essential for the users, which reads "Sets the amount of tesselation of the sky dome. A higher value takes longer to render, but makes the sun look more rounded." If it is, this explanation should be a part of the explanatory text for "Mesh Detail" so that the user can easily identify which is which. Otherwise, i.e., the current text is not needed at all, just removing this text seems OK. My feeling is that we should just remove it. The attached patch (skydetail.patch) removes the said text from the base English (en-us) alerts.xml file, as well as German (de), Japanese (ja), and Korean (ko) translations. Other translations, i.e., Spanish (es), French (fr), and Chinese (zh), don't contain the corresponding help text and hence untouched. NOTE that the attached patch file contains a UTF-8 text. You need a Unicode enabled tool to handle it.
