Data pane: mouse wheel scrolling flickers/jumps when cursor is over field names

Description:

Version: Power BI Desktop 2.159.883.0 64-bit (October 2026)

Issue:
In the Data pane, when a table is expanded and its field list is taller than the pane (vertical scrollbar visible), scrolling with the mouse wheel does not work properly. The list flickers, jumps up and down, and does not move.

Steps to reproduce:

1. Open a report whose model has a table with many columns/measures (around 40 or more).
2. In the Data pane, expand that table so the field list is longer than the visible pane height.
3. Place the mouse cursor over the field names and scroll with the mouse wheel.

Actual behavior:

• With the cursor over the field names, the pane flickers and jumps, and scrolling fails.
• With the cursor on the right margin, next to the scrollbar (not over any field), wheel scrolling works correctly.
• Dragging the scrollbar works correctly.
• Tables whose field list fits in the pane are not affected.

It looks like the hover highlight (and the “…” button that appears on the hovered field) triggers a re-render that resets or interrupts the scroll position.

Expected behavior:
Smooth mouse-wheel scrolling regardless of where the cursor is inside the pane.

Already tried (no change):

• Windows “Always show scrollbars” enabled, Power BI restarted
• Changing report zoom and resizing the Data pane
• Deselecting all visuals before scrolling

Workaround:
Scroll with the cursor on the right margin of the pane, or drag the scrollbar. I am attaching a screenshot for your review.

Thank you in advance
