Created attachment 66456 [details] Video file with SNA mode In attachment video files. I currently can't restart X and change to debug mode, so logs I will send later. Dotted lines vanishes if you don't move a mouse. Continuous line is not correctly too. If you move a mouse, some parts of line are higher than others - vertical sync? It's not shown on video. Autocad 2004, run on wine wine 1.4.1 intel 2.20.5 mesa 7.12.2 kernel 3.5.2
Created attachment 66457 [details] Video file with UXA mode, where works OK
When I want to run Autcad on drivers compiled with debug-mode, X crashes. So I don't have any logs.
Look harder, in particular look on xdm.log, gdm.log or kdm.log where stderr is logged and the assertion captured. But considering that you are hitting miZeroDash, this should be an issue in the core xserver drawing code.
You can look for logs from crash and tell me why it crashes. It's not possible now to create real log, because X crashes in the same moment, when Autocad starts. Crashes only debug version. No-debug is OK of course. I compile it with: ./configure --prefix=/usr --enable-debug=full. Dependencies from debian repos: apt-get build-dep xserver-xorg-video-intel.

You are hitting the assertion fixed in commit 71ac12e9b6ed00c28993637aafd5186a2ba26256 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Aug 27 15:49:59 2012 +0100 sna: Assert that the bo is marked as 'flush' when exported to DRI clients Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
Thank you for your suggestion. Problem is with disapperance dotted lines used to select objects, when I don't move mouse. I see it only when mouse is on move. On video you don't see dotted line at all. Other matter is leave non-refreshed screen - you can see dotted lines there, where they shouldn't be. But it is more rarely. Now, when I create log, I didn't have this problem.

I'm not sure if you understend problem, so I recorded video using external camera. It looks better. Video file with SNA acceleration enabled: http://www.youtube.com/watch?v=8C_DqIqPMv4&feature=youtu.be Dashed lines which are using to selecting objects flicker. If you don't move mouse cursor, you don't see them. I don't have this problem in UXA acceleration. There everything is OK. Current not working configuration: xserver-xorg-video-intel 2.20.15 mesa 9.0.1 linux-image 3.6.9 libdrm 2.4.40 wine 1.4.1
Ah, I thought you had a bug in the dashing code. That looks more like the broken gen4 GPU...
Presuming this is then the same underlying cause as the GPU inconsistencies being tracked by 55500. *** This bug has been marked as a duplicate of bug 55500 ***
Not really duplicate of #55500. Few days ago I noticed this issue on ivy bridge HD4000. Currently I'm not really sure about dashed lines - I must check it. But cursor certainly disappeared during objects selection. Ubuntu 13.10 + xserver-xorg-video-intel 2.99.907
The cursor always disappears, in both the UXA and SNA videos. Isn't that expected?
That's true, this may be expected. I'm used to DraftSight which shows cursor always ;) I will check it more carefully in the evening.
I can confirm - I don't see dashed lines while object selection at all. They don't even flicker.
To put it succinctly: what do I need to fix?
In short - when you select objects in autocad you should see dashed lines which show area of selection. But they aren't visible. Everything other is ok, including mouse cursor.
Found a bug in dashed line drawing. Please retest with 2.99.908.
I think this was fixed in 2.99.908.
