Mousemove while drag-selecting downwards slows down scrolling of grid #23

Open DataGridXL opened 2 years ago

DataGridXL commented 2 years ago

When mouse-drag selecting downwards (mouse outside of grid), edge detection is activated. Only when mouse stays still the scrolling remains in a solid tempo.

When mouse moves during this drag action, even if mouse movement/coordinates should not affect grid scroll speed (eg. mouse only moves horizontally, which should not affect vertical scroll speed), grid scrolling slows down considerably.

v3 does edge detection based on request animation frame, not based on timeouts. Let's make sure to implement a new approach that does not encounter this issue.
