Created attachment 107940 [details] Demonstration of the problem Crashes almost every time I copy a layer and click on a different file to try and paste it to. I have attached a video demonstrating the problem. I have faced this in a previous version as well
Please provide the backtrace: https://docs.krita.org/Dr._Mingw_debugger
Created attachment 107948 [details] Crash log attached I suppose this is what you are looking for..
Hm, I cannot reproduce a crash. Can you please try the 3.3.0-rc.1? https://krita.org/en/item/krita-3-3-0-first-release-candidate/ Download the portable version and extract it. Also download the debug symbols and extract it like the instructions in https://docs.krita.org/Dr._Mingw_debugger This will give more details for our reference if it still crashes. (Also, you can clear the existing kritacrash.log file before testing so that you won't be uploading your previous crashes again the next time.)
I tested version 3.3.0-rc.1. I got an error when I try to close the file after pasting a layer. I have downloaded the debug symbols and copied it to bin as required, but I am not sure how to use it. This is what I got out of Visual Studio on hitting debug: Unhandled exception at 0x00007FFFFD3BCA7A (libkritaimage.dll) in krita.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF. occurred

(Or if you want to use a debugger you can download a copy of mingw-w64 and run Krita under gdb, but this isn't really needed...)
Oh... In that case, where will I find the kritacrash.log file? It is not appearing in %localappdata% or krita-3.3.0-rc.1-x64 folder..

I just realized that the release is missing several files... so the crash log wouldn't be there... You have 3.2.1 installed right? You can go to C:\Program Files\Krita (x64)\bin, and copy these files to the rita-3.3.0-rc.1-x64/bin/ folder: dbghelp.dll exchndl.dll mgwhelp.dll symsrv.dll symsrv.yes After that you can try again, it should save the backtrace when it crashes (it might take a while)
Created attachment 107955 [details] Crash log for krita-3.3.0-rc.1-x64 Oh great! Found and attached the log..
Thanks, though I still can't reproduce it... I am guessing it might be a race condition...
Do you mean rare? If so, is there something that I can possibly turn off to manage this?
(In reply to Dhanesh from comment #11) > Do you mean rare? If so, is there something that I can possibly turn off to > manage this? Well, I can't tell unless I am able to reproduce it... From the videos it looks like you are trying to combine files as layers? You can try using Layer->Import/Export functions instead, they should not trigger this crash.
Ahh.. This works for me! Thanks for your advice & your time! It is interesting though how the crash does not happen to you. Anyway, good day to you!
I tested the bug. I cannot reproduce the crash on pasting, but I can clearly reproduce the crash on closing Krita. It looks as if X11 is trying to fetch the data from the clipboard before closing the app. #0 0x00007ffff5c885c0 in QObject::thread() const () from /home/devel5/kde-install/krita2-deps/lib/libQt5Core.so.5 #1 0x00007ffff76443d8 in KisConfig::~KisConfig (this=0x7fffffffcde0, __in_chrg=<optimized out>) at /home/devel5/kde-src/krita4/libs/ui/kis_config.cc:60 #2 0x00007ffff759cced in KisGuidesConfig::loadStaticData (this=this@entry=0xaefc648) at /home/devel5/kde-src/krita4/libs/ui/canvas/kis_guides_config.cpp:203 #3 0x00007ffff759cf35 in KisGuidesConfig::KisGuidesConfig (this=0xaefc648) at /home/devel5/kde-src/krita4/libs/ui/canvas/kis_guides_config.cpp:67 #4 0x00007ffff78afa86 in KisDocument::Private::Private (document=0x7cd4d40, this=0xaefc5a0) at /home/devel5/kde-src/krita4/libs/ui/KisDocument.cpp:285 #5 KisDocument::KisDocument (this=0x7cd4d40) at /home/devel5/kde-src/krita4/libs/ui/KisDocument.cpp:535 #6 0x00007ffff78ed92b in KisPart::createDocument (this=<optimized out>) at /home/devel5/kde-src/krita4/libs/ui/KisPart.cpp:183 #7 0x00007ffff7685d58 in createDocument (nodes=..., srcImage=...) at /home/devel5/kde-src/krita4/libs/ui/kis_mimedata.cpp:98 #8 0x00007ffff76863f5 in serializeToByteArray (nodes=..., srcImage=...) at /home/devel5/kde-src/krita4/libs/ui/kis_mimedata.cpp:120 #9 0x00007ffff7686ae8 in KisMimeData::retrieveData (this=<optimized out>, mimetype=..., preferredType=<optimized out>) at /home/devel5/kde-src/krita4/libs/ui/kis_mimedata.cpp:140 #10 0x00007ffff5c848e4 in ??
