Description Larry 2016-01-16 16:38:01 UTC

Scrolling the folder/file list in icon, compact or details modes scrolls the window very slowly.  All other applications scroll properly.  For comparison, opening /usr/share with Konqueror and scrolling with the mousewheel results in a shift of 19 files / wheel roll while only 1.5 files are scrolled with each roll in Dolphin.  The same problem does not exist in Fedora 22 or earlier.

Reproducible: Always

Steps to Reproduce:
1. Open Dolphin to a directory with many entries.
2.Roll the mousewheel to navigate lower.
3.

Actual Results:  
Around 1.5 filenames are scrolled with each mousewheel.

Expected Results:  
At least 10 or more filenames should scroll.

While troubleshooting this issue, I came across the use of the shift key while scrolling and Dolphin is now usable.  I wasn't aware of this change in behavior but it is interesting.  I stil don't believe that it is a duplicate of the other burg.

Fedora is using libinput as far as I know, so I marked it as an duplicate of bug 357618.

Comment 4 Larry 2016-01-23 16:34:04 UTC

libinput-list-devices does list the mouse so it must be.  I'll review the RH bugzilla and will update if I think it's different.

Thanks.
