i'm using redhat6.0 with the included SVGA-server and am experiencing problems that i also had on the same machine with suse-linux and under windows (possible hardware bug). i use a s3-virge/dx graphics card with 4mb of ram at 1280x1024 @ 16bit and about 75Hz. every now and then, usualy on viewing pages with large amounts of 12-pt times text, the fonts - all of them, even the window titles - get garbled in the worst of ways. switching back and forth to and from the console get things back the way they should be. the problem seems to be hardware as it is cross-platform and quite easy to reproduce. i once heard there was a workaround - some option in the configuration regarding buggy font-caching. there is also a similar bug classified under netscape. thanks in advance
there are hardware problems with some virge cards, and you appear to be one of those who has this problem. We suggest you continue to upgrade to later versions of XFree86 as they become available, but the best solution would be to get a different video card -- cards which perform better than the virge are now available for under $20.
