In the lister I always experience lag when scrolling through many files - under two circumstances:
I have selected a few files. Selecting more worsens the problem.
There are multiple files visible that have a label association with specific (background?)color settings.
I have a label with yellow text on red background associated with executables using
Maybe noteworthy that I have a pretty long label association with media files
Here's a 60fps screen recording which illustrates the problem as I scroll through %systen32%.
Note how smooth the scrolling is when threre are only dll files on screen. Also note how horrible it gets once I press CTRL+A.
Can I supply any more information to help pinning down the problem?
I'm on latest beta, OS is Win8.1 Pro 64bit.
//EDIT:smooth scrolling in "Prefs / File Displays / Mouse" doesn't make a difference.
