| Summary | 0016404: GridView.restoreColumns can take more than 6 seconds in some cases | ||||
| Description | 1) Open a root folder (e.g. your main Music folder including all tracks) In my case it is [Music > Location > Network > NAS > Music] 2) Click "Display folders content recursivelly" button on the toolbar so the path on the navbar is expanded to [Music > Location > Network > NAS > Music > All] like this https://www.dropbox.com/s/p0f01m7egww4fdg/screenshot%202020-02-26%2010.40.36.png?dl=0 3) Click a folder in the grid to navigate to the particular folder 4) Click "Back" button on the navbar => 8 seconds UI freeze !! Inspecting the performance using DevTools you can see that GridView.restoreColumns took more than 6 seconds, see: https://www.dropbox.com/s/cw1090td940yf2o/screenshot%202020-02-26%2010.36.37.png?dl=0 a) it seems to unnecessary destroy and draw _all_ the LV divs again (11K tracks in my case) although the tracklist is not visible at all (only the folder grid part is visible) b) it seems to unnecessary restore the columns that the LV has already set (as used from controlCache) ! | ||||
