This is probably not a bug but a configuration problem of some sort. Text using _a4font does not display properly. For example, text displayed after pressing F11 or on the console line after pressing TAB appears garbled. Other fonts are fine. Any ideas what I should check? Thanks.

Is this related to a specific game?

The problem occurs all the time. For instance, even opening the level editor, creating a level with a small cube, building the level, running it, hitting F11 results in the garbled font.

My system is Windows XP Home Edition (5.1 Build 2600),
with ATI Radeon X800 PRO AGP,
Direct X 9.0c

I had exactly the same problem. Though my problem was also with panels as well as text. It occured whenever the overlay flag was set. The text appeared garbled. Whenever I had panels with the overlay flag, there were serious appearance problems. I tested the game on another computer and it worked fine. I replaced my video card and the problem was fixed. I also had the problem with playing games, such as Motocross Madness 2, the text appeared garbled where it displayed the players names etc. It could be your video card. I'm not sure what my old one was. Test it on another computer and see if you still get it.

We don't have a Radeon X800 among our test systems yet, but the problem does not occur with all other sorts of Radeon cards that we have here. Maybe it is indeed related to a particular driver version that has a bug with overlay images of a particular size (the _a4font is very small).

Please update the driver to the latest version from the ATI website.

Have you checked whether the same problem occurs with other 3D games also?
