Hi, I've experienced this problem on Wireshark in which all rows in the UI will suddenly expand to around 6x the standard row height. (I'd upload a screenshot except I don't have permissions)
Unlike column size there doesn't seem to be a way to readily change the row size, and reloading the pcap is the only solution. This becomes very arduous and I usually give up whatever I was trying to do.
I found these reported bugs which sound similar to my issue, but it's beyond my ability to follow the technicalities. I've also noticed, as reported below, that the expansion happens when I click on, or simply scroll past, a particular packet.

Bizarrely this problem seems to persist even through updates and clean re-installations. Perhaps I can add a line to qt.conf to permanently fix the row size to 1? At this stage I'd be very happy with any solution, even a "hack"
