SUMMARY

This specific SVG file of an icon puts Krita in a state of infinitely increasing memory used until I have to kill it. For testing purposes I've loaded it into Inkscape and saved it. This worked without any problems. This happened in 4.4.x too but didn't change when I upgraded my installation.

STEPS TO REPRODUCE
1. Load the file

SOFTWARE/OS VERSIONS
Windows: Windows 10 x64

I can confirm this in 5.0.6 and 5.1.0-beta2, but, interestingly, not with git master. That branch must have a fix somewhere that didn't get backported.

The bug looks really familiar. Let me check this.
Comment 3 Halla Rempt 2022-07-20 07:44:08 UTC 
I'm pretty sure you already fixed this somewhen in master :-)
