X.org Log of the R600G run

Git snapshot of: Mesa/ee09c1e1

I've tested Mesa's r600 DDX (xorg state-tracker) with X.org 1.11.0 and KDE 4.6.5. Immediately after KDM is launched, the mouse cursor is distorted (wrong proportions, longer than wide) and is overlayed with a blue strip pattern (horizontal) in a rather large square area around the actual cursor. Underneath the distorted cursor is visible.

There are further graphical glitches (like when you open something in less, Pos1 and End seem to have no effect, only when you press an arrow key, the display is updated partially, after the second arrow key press, you get a full update, waiting doesn't help) or slow reaction to pressing keys (entering something takes like a felt extra second per key, ie. between pressing the key and seeing the result on screen), but I guess those are different bugs, right?

If you need further information, just let me know.

With the latest Mesa Git snapshot (4a96a02d) there is some improvement: the blue overlay is gone, now I've a distorted (too long) cursor. It looks like there is some interleaving problem, because every other line is transparent.

If the cursor would normally look like

###

It now looks like:

Please also note, that I can't get a screenshot of this. Whenever I use KSnapshot, the cursor looks correct in the resulting screenshot (ie. without the additional transparent lines).

Still there as described in comment #1 with the following stack:
Mesa: Git/09a92e37
libdrm: 2.4.26-1
X.Org: 2:1.11.1.901-2 (1.11.1.901 (1.11.2 RC 1))
KDE: 4:4.6.5-2
GPU: 1002:9553

The X.Org log hasn't changed (except for the reported versions). Let me know, if you need further information.

xorg-r600 was removed (<http://cgit.freedesktop.org/mesa/mesa/commit/?id=da82d7b6ba0c7e2e2d576c58fea4fbfa132511cb>) → close this bug.
