[Dri-users] Minor problems with new CVS trunk

[Martin K. <mar...@ng...>]

Hi,

I updated my XFree4 to the new trunk last night, and it seems to work
wonderful except for two minor problems when running in 3d mode:

The first is a rather curious one:

Whenever I have wmmail (a mail monitoring app for Window Maker)
running in the background all text output gets scattered. Hard do
describe, but the text blinks at a very fast rate and pixels disappear
from time to time. This occurs in the Quake3 menu screens for example,
or when running bzflag. Not enough, as long as wmmail is running in
the background I see a *huge* hit on my frame rate (drops from ~30fps
to ~10fps). As soon as I kill wmmail, the problem is gone. Weird, he? :-)
Took me hours to find out that it was wmmail...

The second is rather annoying:

3D rendering seems to be *very* sensitive to programs running in the
background now. As soon as I start a CPU monitoring program for
example, or even a simple clock, I see my frame rates jumping around
widely. Hard too describe too (especially in English :-)). Imagine you
are running Quake3 without bots and stand still at one point of the
map just looking at a wall.  Now I see my frame rates jumping around
from ~10fps to ~30fps pretty fast. Killing all these background apps
gives me a constant frame rate of 30fps. I also tried to "nice them
down" but the effect is still there.

Another problem is that I get some kind of "movement stuttering". When
running forward for example your movement gets stopped for a small
time and you start running again. And yes, killing those little
monitoring programs solves that problem too, but I will miss my
desktop clock. ;-)

On the positive side:

Huge performance increase! Took me from around ~20fps in Quake3 to
~30fps.

BTW: I had the official XFree4.01 installed before and did not
see any of the problems mentioned above.

Regards,
  Martin
