[Interest] SVG is loaded with invalid dimensions on some machines

[Alexander Dyagilev]

Well, I was able to reproduce the issue.
1. Launch app.
2. Change system zoom settings from 100% to 125%.
3. Done. The issue is here. After restarting app - issue is not reproduced.
So, just a guess, on 2-monitor system this zoom settings changes at runtime
(maybe app is started initially on some monitor and then moves to another
one with different zoom setting).
*Question is*: is it possible to disable this auto-zoom thing for a
particular image or at least globally?
