- changed title to Scroll-wheel navigation (inc. opt-scroll zooming) extremely slow
Scroll-wheel navigation (inc. opt-scroll zooming) extremely slow
USE CASE: WHAT DO YOU WANT TO DO?
Option-scroll to zoom
STEPS TO REPRODUCE AN ISSUE (OR TRIGGER A NEW FEATURE)
- Open the large_6kx6k.txt file
- Hover over the middle of the matrix
- Hold down the option key and scroll up quickly & continuously until zoomed all the way in
CURRENT BEHAVIOR
Zooming appearance is extremely slow. Updates happen tens of seconds after you stop scrolling. Zooming in a bit and scrolling the matrix up/down/left/right also is slow. Scrolling by dragging the scrollbar thumb or zooming using the +/- buttons is WAY faster.
EXPECTED BEHAVIOR
Scrolling and zooming using the scroll wheel should be fast and smooth regardless of data size.
DEVELOPERS ONLY SECTION
SUGGESTED CHANGE (Pseudocode optional)
This used to be a very snappy/smooth/quick feature. Hunt back through the commit or PR history to find where the lag was introduced and start there by looking at the changes that caused the lag.

COMMENTS
Seems that dragging the scroll thumb is slow if you're zoomed in only a little.
