Description denisgolovan 2011-01-13 08:05:18 UTC

I am experiencing a regression for MetaTrader program under latest Wine.
I am using Gentoo Linux with latest intel driver build from git.
See attachments for comparing 2.11 and git (2.14+) versions.

libdrm is built from git bad5242a59aa8e31cf10749e2ac69b3c66ef7da0 commit.
xf86-video-intel is build from git fd9235ebe03a01982238cdd6e8b55f613e14b6af commit.

Please retest with 2D driver as of:

    uxa: Simplify Composite solid acceleration for spans by only clipping once.
    Unlike the previous commit removing this style of code, the code in
    this one was originally wrong, and would fail to clip in the second
    pass of clipping when y was > pbox->y2.

Unfortunately, that commit does not help.

I rebuild both libdrm and xf86-video-intel from git.
The latest commit was from 8f97157d2e807d6c9acb521ec59757f419e6518b

The commit you refer to is in.

    uxa: Remove the attempt to use the 3D pipeline for core rendering
    The attempt was still ridden with bugs, such as
    A fresh approach was taken with SNA, but in the mean time before that
    can be enabled downstream, restore correct behaviour.

Comment 9 denisgolovan 2011-07-03 02:47:17 UTC
I acknowledge the fix.
I tested both with and without sna. It works fine now.
Thanks a lot.

P.S. For those interested - I used x11 overlay, upgraded xorg-server to 1.10.2 and enabled sna use flag for xf86-video-intel
