-I activate dyntopo
-with subdivide collapse and brush detail to 28 or 50 per cent
-I sculpt with speed lines and in this phase the cursor of blender block his movement, but the system cursor go well, blender freeze without error signal, i have see terminal. Anyway i terminate blender with system monitor.

i have try to remove that the brush size is regulated from pen pression and from the first tests apparently blender not crash

Does it happen for you with default cube scene?
Does using blender-softwaregl makes any difference for you?

ok i have try, this is easy to reproduce
1 I have try with default cube , same error
2 I have try software gl and not make difference

another think , I'm on ubuntu with proprietary ati driver, catalyst,
If you want, I can try with ati open driver, but i have impression not are drivers,
if you want i can test on another maschine with old nvidia

Yes, please test it on another machine and see if it's reproducable there.

ok same bug on amd 4core 3100mhz with nvidia gt 250 if i remember with ubuntu,
the problem can is relative to driver wacom of linux?
I'm use a intuos 4. Later i try to change tablet.

ah with wacom bambu the bug is very fast to activate.
my idea is that the sculpt dyntopo have problem

i have try now, but the bug not is present, probably is driver ati app sdk 3 beta

@stefano di filippo (frogger), don't get what you mean with your last comment. You mean you can't reproduce the bug anymore?
