--- Comment #2 from ocumo <kxk-ocumoatbugs...@lugosys.com> --- Thank you for your reply. I didn't collect the backtrace. The one think I can say immediately is that ALL the troubles I have found with krita 4.x are _only_ happening when I use any krita 4.x *appimage* with my Wacom Cintiq display tablet. That is regardless of my system being kubuntu 16.04 or kubuntu 18.04. To make it as clear as possible: 1. It is not possible to use a Wacom Cintiq 27QHD Graphic Tablet in (K)ubuntu 16.04 or 18.04 with any appimage version of Krita >= v4. 2. If Krita v4.x is installed using the kritalime ppa, then it is possible to work, only with a couple of very minor issues, but with no significant issues. So: As soon as I finally was able to use the kritalime ppa and installed krita 4 from there, I confirmed that none of the the worst issues I have been experiencing with the appimage versions happened. But because I have been wasting so much time in trying to eliminate any possible causes from my side, and in the process nearly drying out my adrenal glands of any cortisol they might have left, with no help, you would understand what a relieve I had when I finally found a way to work with krita >= 4 and the Wacom Cintiq tablet. Whether this makes any sense for a bug report I don't know any more, but whenever I try any appimage of 4.x.x, it will crash and/or provoke strange issue as reported in this thread, as soon as I get my bare fingers on the touchscreen. So: yes, I can reproduce the thing. The question is, I would have liked a bit of guidance as to how to proceed, as in another bug report I asked, but unfortunately you guys are overwhelmed with so much work for a small but brave team of talented devs, that I can't expect you to prioritize this request. I do understand that I might be the only person on the planet that spent a few thousand euros on a Wacom Cintiq 27QHD Graphic Tablet to use it with Krita exclusively, and in Linux, although I do have a Windows partition with Photoshop in it. But I rather used Krita v3.x than Photoshop: it's been more than one year since I haven't logged on to Windows and I still think it's not worth doing that. So fixing whatever it is in appimages that doesn't like Wacom Cintiq tablets for only one user doesn't make any sense, especially when the installed versions from kritalime ppa do work reasonable well. Believe me, I am not going to boot any time soon my Windows partition, let alone switching to my (working) Photoshop CC2015. And to anyone interested and wondering: Yes, any cent you would invest in a Wacom Cintiq is absolutely the best investment you would have done in many years! You won't regret. You have to try some day. In Krita (from ppa)! -- You are receiving this mail because: You are watching all bug changes.
