Hi, Both my home and college computers are running LyX 1.6.3 (3 June 2009) on Windows XP, installed with the default installer. I see the following problem only on my college computer [but I have mentioned my home PC in a couple of places for comparison, you can ignore if you like]. This is about fonts as they appear in the LyX edit window, *NOT* in the PDF output (or instant preview).
At college, screen fonts in LyX seem to be distorted, even when I have caching turned off. I attached a couple of examples to this email, with white background and no zooming (although the problem also occurs in my favoured settings of 120% zoom and light blue background). It seems that there are two different things going on: 1) A one-pixel wide column on the left and right edge of most characters is being truncated. This looks particularly silly for thin characters such as l and i. 2) All the pixels are converted to grey (they start off coloured because this is how ClearType shades subpixels). 2 is absolutely not a problem. I only mention it in case it's related to 1 (perhaps it's the cause?). It happens whether pixel caching is on or off, although when it is off the grey pixels are a bit darker. [home PC: I *thought* that on my home PC 2 only happened when I turned pixel caching on (in fact I leave it on there for this reason, since then the font better matches the instant preview); I can't check this since I don't have access to that PC for the next few days.] 1 is a problem! The text looks very wrong and is hard to read. [home PC: this definitely does not happen there; the text looks fine.] Interesting point I discovered: this happens even in LyX dialog boxes (both the labels and edit boxes, which use Tahoma 8pt). The problem is not so noticeable there since it's not so bad for small fonts. In fact my workaround for now is to use small fonts for editing, but this is a strain. Any idea what might be happening? Is there some font engine that LyX uses that maybe is out of date on the computer I am using? I can't try the other installer or turn ClearType off because I don't have the privileges. [I have ClearType turned on at home, so I don't really think it's that anyway.] Thanks in advance, Jim
