George Rachor:
 |Pentium 75 with Mach 64 video running FREEBSD 2.2.6
 |
 |FXTV works well as long as I have another window partially covering up the
 |the fxtv window.  If I complete uncover the fxtv window I seem to get
 |remanants of two images side by side within the window and performance
 |drops signifacantly.  Anybody seen this?
 |
 |Just joined the group so don't know if this is talked about already.

When the window is partially occluded, Fxtv uses ximages to transfer images
to the display (i.e. it sends them through the X server).

When the window is unoccluded, it uses direct video.  That is, it
configures the video card to dump the pixels directly onto the frame
buffer.  I'd have to see your screen to know exactly what's misconfigured.
If you're in 24 or 32bpp, you might try tweaking the Bpp settings in the
Fxtv resource file.

Odd that you should see reduced performance with direct video.  Two things
that might be slowing your system down: the 25MHz PCI bus (vs normal 33),
and do you by change have a DRAM Mach64 (e.g. Expression, etc.)?  I'm
assuming it is a PCI card.

Try reducing the size of your TV window when it is unoccuded and see if
things get better.  I'd be interested in seeing a snapshot of your desktop
with the double-image.  Be sure to do a Refresh Desktop before you grab
your snapshot though so we don't have leftover trash in the snap.
