Memory growth (then crash on Windows) if grid used and Document properties open

Summary:

I used to use Inkscape around v0.9x and had no problems with it. I just installed the latest version (v1.1) and was extremely disappointed to find it unusable.

It's both extremely laggy, and crashes every few minutes. It's difficult to give a specific reproduction since it just crashes constantly. Sometimes it hangs. Sometimes it just terminates.

Steps to replicate

1. Start Inkscape
2. Create a grid (#)
3. Open Document Properties
4. Create a rectangle and drag it around

What happened?

• Fast memory growth (10MB/second)
• lag (reported in #2107 (closed))
• on Windows, at 700 MB, Inkscape crashes, with this backtrace inkscape_backtrace.txt
• Some investigation: #2585 (comment 611929914)

What should have happened?

• No crash, no memory growth, no lag
