Description

I've noticed a large amount of freezing/stuttering that occurs while scrolling in directories with many video files. I came across the following thread on the XFCE forums where someone had the same issue: https://forum.xfce.org/viewtopic.php?pid=49930

My media folder has several hundred videos, and when scrolling up/down it will freeze and become unresponsive for anywhere between a second or two to 10 or 15 seconds before finishing the scroll. All videos in the folder already have thumbnails generated and displayed. During the freezing, CPU usage for both Thunar and Tumbler is very low.

It started happening recently, around the time Tumbler got updated for my OS (to 0.2.3-1 on Fedora). Thunar hadn't been updated in months and this appears to be related to Tumbler as when I downgraded to an older version of Tumbler (0.2.1-1), I no longer experience any freezing.

Version: 0.2.3
