...m) { /* Use fragment program generated from fixed-function state */ } block. Interestingly enough if I allow malloc(0) to proceed from ElectricFence, then the glretrace runs fine, and even renders correctly, where as running the same gl command stream from libreoffice impress leads to missrendering on nv3c. So 2 questions: 1) Is it normal / expected for st_translate_program() to get called with an empty but not NULL proginfo->Parameters resp. num_immediates == 0 ? If not where would I begin to look for finding the culprit of this ? 2) Since the glretrace does work outside of libreoffi...

I'm not going to do that, because I really not that competent for that, even if i know about c programming. I also think that this can cause missrendering, and not crashes, but it also seems that there aren't stored any messages on the crash, maybe it crashes before it can write something to the harddisk? But thank you for your help. Martin

Well, if compiz/something else *crashes* (i.e. segfault/sigbus/whatever), it's likely there's a log of it. Perhaps...

Hi there, Sometimes my computer crashes since i use now ubuntu 13.10 with unity/compiz. dmesg tells me: [ 686.209019] nouveau E[ PBUS][0000:00:0d.0] MMIO write of 0x00000000 FAULT at 0x00b020 and later: [ 1425.565441] nouveau E[ PGRAPH][0000:00:0d.0] ERROR nsource: DATA_ERROR nstatus: BAD_ARGUMENT [ 1425.565462] nouveau E[ PGRAPH][0000:00:0d.0] ch 3 [0x00056000 compiz[1970]] subc 2

Running Tomb Raider on Nouveau I found some flicker caused by ignoring precise modifiers on variables inside Nouveau. This series add precise/invariant handling to TGSI, which can be then used by drivers to disable certain unsafe optimisations which may otherwise alter calculations, which depend on having the same result across shaders. This series fixes this bug in Tomb Raider and one CTS test
