Description carinatoocool 2019-09-10 06:17:24 UTC 
SUMMARY
I experienced the crash when using large brush size to draw. Krita would freeze and closes down unexpectedly.  . The brush do lag in some occasion but I don't think it should cause crash since in other similar software (such as Paintstorm Studio and Photoshop) the program will now quit and may only froze until the stroke catch up with the brush cursor. In other cases, Krita would quit even if the stroke of the large brush is not that severe. I am using Krita 4.2.5 however I had encounter similar crash in the beta version of 4.2.6.

STEPS TO REPRODUCE
1. Create a fairly large canvas, A4 or A3 at 300 dpi, with rgb colour model and 8 bit integer channel.
2. Use any brush, preferably the textured one. I have tried the dry roller brush and some of the chalk brushes. 
3. Increase the brush size to very large of maximum.
4. Starts making huge stroke. I would change the colour occasionally before making more strokes.
I made a video showing how this crash can be reproduced.
https://youtu.be/B1-1wFFAC9M

OBSERVED RESULT
Brush stroke lags a bit but not too terribly. Then after making a few more, Krita would froze for a few seconds and then close down without any warning. It just quits unexpectedly.

EXPECTED RESULT
Brush strokes would lag but will not actually cause Krita to quit. The program may froze but will return to normal once the stroke had caught up with the brush cursor.

Krita crash log
Comment 2 Dmitry Kazakov 2019-09-10 10:39:10 UTC 
Hi, Carina!

This bug is caused by hardware bug in AMD Ryzen 5 3600 CPUs. Its hardware random generator does not work, therefore Krita generates the same swap file name every time and (since the file may exist after previous runs) fails to open it. We have a workaround for it, but it will be released only in Krita 4.2.7 in October.

For now you have two options:

1) Either use nightly Krita builds from here, they have a workaround for AMD CPUs: 

https://binary-factory.kde.org/job/Krita_Nightly_Windows_Build/

2) Or before running Krita, check the contents of this folder:

C:/Users/Carina Sasmita/AppData/Local/Temp

And remove all the files starting with "KRITA_SWAP_FILE_". It will eliminate the problem until the next Krita crash or non-graceful shutdown of the operating system.

Hi Dmitry

Thank you for the reply, I've checked out other threads and I have no problem in waiting for the 4.2.7 release, in the meantime I might just use the nightly builds. Sorry if this bug has been discussed in other reports, I've searched for similar problems but I thought it is not reported yet since I use Krita mostly for drawing and painting and only noticed the bug when using the brushes.
Thanks again for the fast response, really enjoy using Krita.

Regards,
Carina
