I checked out 1.6 on friday, and noticed some problems:
* Invisible document Brought up two documents with "lyx doc1.lyx doc2.lyx" doc1.lyx seemed normal, but doc2.lyx came up with an empty main window! The scrollbar was present though. I scrolled through half the document, and suddenly the document became visible. doc2.lyx is the longer document of the two, more text and more paragraphs. * painting errors I saw this a couple of times, but can't reproduce reliably: while typing into the middle of a paragraph, the new text is painted on top of the old, i.e. the old is not erased first. So the line gets very black after typing a word or two (this changes the interword spacing on the whole line, which is overlayed on top of the old line layout.) When the line breaking changes, the entire paragraph messes up the same way. Scrolling a little fixes everything. Using qt 4.3.2 from debian linux. Helge Hafting
