[Nouveau] Text sometimes missing on NV18 based laptop

[Clemens Eisserer]

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
