Description Buovjaga 2019-05-14 08:14:37 UTC
1. Open attachment 125010 [details]
2. Scroll it past page 16

On Linux it freezes the whole system for a moment. Already seen in 5.3.0 (on Win 10), although I have to scroll past 16 and then back again to really hit it.

Seen in 5.1.6: https://bugs.documentfoundation.org/show_bug.cgi?id=99800#c6

Still repro, but it doesn't freeze the system. Lowering severity.
