Nouveau - Jul 2014 - Text sometimes missing on NV18 based laptop

Hi,

On my NV18 based laptop I experience artifacts related to text
(however, 2D performance is really great these days):
- With grayscale AA text is sometimes missing, often visible on the XFCE desktop
- With subpixel (rgb) AA, even non-text related occur (icons are
misrendered, ...)

I've reported the issues here:
https://bugs.freedesktop.org/show_bug.cgi?id=81283

With noaccel it works fine, however it is annoyingly slow.

Is there anything I could try to track these issues down?

Best regards, Clemens

I know NV1x isn't anything spectacular or exciting to work on, however
on that notebook I don't have any choice.
Therefore I would be really grateful for advice how to narrow the
issues reported down.

Even finding a way to selectively turn off the accel-paths which cause
the issue would be a big win, as with noaccel the system is barely
useable.

Thank you in advance, Clemens

The problem isn't that the hardware is old. The problem is reproducing
the issue. Unfortunately my NV18 died (currently looking to replace
it), but with a very plain WindowMaker + no weird anything setup, my
recollection is that everything worked fine. And I wasn't willing to
take the plunge and install/use gnome... perhaps I should do that next
time with a throw-away account so that I don't mess up my stuff. I
guess XFCE isn't as heavy though.

I thought I provided some advice in the bug on how to do just that.

I'm going to set up an old P4 system with a GeForce4 -- I'll see if
there
is of those suggestion that Illia made that I can try out...
