I'm reporting several different rendering issues with the equation editor.
Long equations disappear when I download a document as a PDF or .doc or when I publish it to the web. For example, contrast this screenshot
of a document with this screenshot
of the document when downloaded as a PDF. Note that the second equation has disappeared entirely. A little investigation led me closer to the source
of the problem.
In-line equations appear much different in Google Docs than they do in downloaded PDFs. For example, contrast the first equations in this screenshot
and this screenshot
. Note that the Google Docs version is pretty and readable, whereas the PDF version is confusing and difficult to read. In this particular example, it's only a small problem, but with more complicated equations, it can render a sentence completely impossible to read in the PDF version.
Equations sometimes cause problems with the cursor in Google Docs. I'm not quite sure when this bug occurs or the details of how the cursor is messed up, but here is a screenshot
in which some text appears to be selected, but other text is in fact selected, as evidenced by the editor claiming that the selected text is blue.
There appears to be one rendering engine used when equations are first loaded and a second rendering engine used when one starts editing equations. The differences between these two rendering engines are severe. For example, consider this screenshot
of a document that has just been loaded. Contrast it with this screenshot
, taken after adding and removing a character from the first equation on the page. Note, for example, that the phi inexplicably changed from capital to lowercase. Finally, a screenshot
of the document after adding+removing a character from each equation on the page.
Overall, the equation editor has lots of great features, but is so buggy that it is unusable. I will not be using Google Docs in the future for writing up mathematical documents, and I am sad about this. Please fix these problems and the other problems that I'm forgetting about, because believe me, there are more.
