--- Comment #4 from ocumo <kxk-ocumoatbugs...@lugosys.com> --- (In reply to Boudewijn Rempt from comment #3) > Please get back to us when you've done those tests! I haven't been able yet to test in the Kubuntu 17.10 system, but in the meantime I have installed the Cinnamon package in my main one, just to see if I get any more clues. I launched it from the console, to monitor (and record) the output of the session. At first, it looked promising, since I couldn't crash it with the same sequence of events as described previously for KDE, Xfce or Enlightenment. The happiness lasted only for five full minutes: While drawing, I tried one of my own brushes (nothing special, just a small change on a basic default brush) and I saw this error repeated like 12 times while painting: `Accessing uninitialized random source!` ..so I changed to an 'official' brush and kept drawing for few more seconds and when I tried to zoom in with the touch gesture then Krita hanged immediately; no more response from any input. I was simultaneously monitoring the system with htop: The only value for which I am not sure is the resident memory (RES column) for one of the two krita processes: '1379M', which accounts to 8.6% of my total system's RAM (16GB), according to the MEM% column, so that would be around 1.3GB. The other process shows '2600' (no units) which shows in the MEM% column as 0.0, and frankly is lower than many other processes so because the man pages don't say anything about units, I will have to assume that this is MB or lower unit (I don't get the htop's units logic). As for CPU%, both processes showed 0% at the time it crashed/hanged. I have a snapshot (picture) of htop at the moment of crash, let me know if that's interesting to attach. Also: is this 1.3GB typical/acceptable for the resident memory (htop's RES column) or should I somehow try to focus more in the memory, as Wolthera suggested, perhaps a memory leak? Bottom line, so far: Krita 4.0.0 crashes/hangs in all flavors of desktop environment that I have, when using a Wacom Cintiq touch display. The problem varies in severity: from taking down (freezing) the entire X system in KDE, to allowing to draw some 5 minutes and hang only Krita, with no exact identifiable pattern of what triggers the crash or how to reproduce it, other than (_apparently_) use fingers to interact with krita, as in a zoom gesture (Cinnamon), using the popup palette with fingers (Xfce, Enlightenment) or possibly those or another one in KDE. As I am having more information, I'll update, but for now I definitely am not using Krita 4.0.0 except for these experiments. I can't be more impatient to update my Kubuntu system to v18.04 in the hope that things might be better then. The stable release is supposed to be on the last week of April. -- You are receiving this mail because: You are watching all bug changes.
