        <pre>Description:
After the latest update today my Calc is extremely slow. It doesn't really
matter what I do, but it's clear when I open a file it's struggling with the
content, for example with displaying the red squibbly lines under text. It also
looks like the fonts have changed, but can't really tell for sure. I've tried a
restart, but that doesn't help.

I'm running Windows 10 Pro, Intel i7 3.4GHz, 16GB RAM, 64bit

Steps to Reproduce:
1. Open Calc
2. Try to navigate the file
3.

Actual Results:  
Every action in Calc is lagging.

Expected Results:
Not lagging in small files like it did before the update I installed today.


Reproducible: Always

User Profile Reset: No
