Title:
Thumbnails are returned one by one to QML thus already existing
thumbnails can be blocked
Status in Thumbnail generator for all kinds of files:
Confirmed
Status in qtdeclarative-opensource-src package in Ubuntu:
In Progress
Bug description:
Thumbnail requests made via the QML thumbnailer image provider are enqueued
and processed one by one which has some nasty UX consequences:
1) if a thumbnail already exists it won't be returned immediately if other
thumbnails are ahead in the queue
2) video thumbnails are much slower to be generated so if one is being
generated, all other thumbnails are blocked until it finishes
This issue would be alleviated if not for
https://bugreports.qt.io/browse/QTBUG-37988
But even with the Qt bug fixed, 1) would still be an important issue in many
cases
