<pre>Description:
When you drag, without releasing, a sheet-tab in the tab deck at the bottom of
a Calc window, and move it around over the other tabs, guiding triangles |> <|
show up to indicate where the tab will be placed if you release it.
However - when these triangles are re-painted, as you move your mouse - some
pixels remain painted black when they should have been cleared.
A comparison of screenshots will follow.
Steps to Reproduce:
1. Open a new LTR document with LTR UI.
2. Add several sheets, to have, say, 5 sheets in total.
3. Select the first (leftmost) sheet-tab, with you mouse - keeping the mouse
button down.
4. Drag the tab slowly to different positions in the tab deck, back-and-forth
Actual Results:
You always see at most one pair of triangles, and no "vestigial" black triangle
pixels from previously-appearing triangle pairs.
Expected Results:
You see pixels from previously-painted triangles where the triangles are no
longer present.
Reproducible: Always
User Profile Reset: No
Additional Info:
Observed with:
Version: 7.1.0.3 / LibreOffice Community
Build ID: f6099ecf3d29644b5008cc8f48f42f4a40986e4c
CPU threads: 4; OS: Linux 5.9; UI render: default; VCL: gtk3
Locale: he-IL (en_IL); UI: en-US

Note that there are also issues with tab dragging and triangle painting in the
context of RTL UI and/or RTL sheets. This is a different issue, although there
might be some relation.</pre>
