Created attachment 118387 [details] GDB text SUMMARY The transformation tool options "cage" and "warp" have no visual updates of the changes, can't tell what's been transformed until a few moments later when the full modification takes places (see video, last part of it demonstrates). Applying the transformations changes will most of the time crash Krita. The other options seems to have no issues. STEPS TO REPRODUCE 1. Make a new file (or open existent) and select transformation tool. 2. Select either the Cage or Warp transformations and try to transform any shape. 3. Apply changes. https://drive.google.com/file/d/1v4zuS-vlg2ewo04lCPCBnRcLpaY5_smQ/view?usp=sharing (I keep moving mouse to indicate that video is still recording :) ) OBSERVED RESULT While trying to transform, there would be no visual feedback/update of what is been changed. Applying the final changes (once the canvas updates) it will most likely crash Krita. EXPECTED RESULT Been able to see what is been changed (normal behaviour).

I've just tried this with the latest 4.2.0 pre-alpha (and the 21st February build) and did not have this problem or any problem with the Warp or Cage transforms.

Can't reproduce this either at the moment, even with a 3000x4000 file... Do you have instant preview on, or can you still reproduce it with the latest builds?
Thanks for checking Ahab Greybeard, Wolthera. Just built right now (Version: 4.2.0-pre-alpha (git d7c5312)) and the there is some changes. Now I can see the canvas been updated as I transform. Still can't apply any transformation as Krita will crash right on click. What I just notice is that turning off "canvas graphics acceleration" makes the crash go away, turning it back will bring back the crash. I'm not sure what's behind, a OpenGl problem maybe? And if so, would it be Krita or the nvidia drivers?(in my gpu legacy now on Archlinux).
Thanks for your comment! Automatically switching the status of this bug to REPORTED so that the KDE team knows that the bug is ready to get confirmed. In the future you may also do this yourself when providing needed information.
I am not able to reproduce this either on my Ubuntu 18.10 on the master branch. With openGL on or off. Maybe this is something specific to Arch linux. Someone with that distro might have to test it out.
Just an update, the krita I build locally still shows the same behavior as described in my last comment. The Appimage though (4.2.0-pre-alpha (git 6448150)) works just fine even without a clean setup (keeping the .local/krita folder as is). I guess whatever Arch has newer than the appimage makes the difference, maybe qt? If you guys need me to do something else just let me know. :)
All right! can't reproduce this any longer, not sure what build changed it but as of today things are working normal again, thus closing this one, thanks for checking and sorry for the trouble. :)
