Created attachment 180621 [details] test file Windows 10 only... Compiled with VS2019 16.11.15 and cygwin When dragging a selected text in the Calc formula bar, the text cursor is not well managed and we have some graphic artifacts. Disable lto compilation option in autogen.sh command solves the bug. It occurs with old LibreOffice version too. It seems independant from the hardware, it happens on intel UHD graphics, Vega 8, Radeon and in Virtualbox. Disable SKIA has no effect. To reproduce - Enter some text in a cell, multiline text is the best - go to formula bar, your text is displayed in it too. - select text with left mouse button - when text is selected, move mouse cursor on it, press left mouse button and begin to drag the text Expected : text cursor follows mouse cursor without artifact Effect observed : some black rectangles where cursor is moving.. See video

I can confirm this in Linux as well (using kf5). So this is not Windows-only. Dragging the text in the formula bar creates these artifacts as shown in the video. System info: Version: 7.3.3.2 / LibreOffice Community Build ID: 30(Build:2) CPU threads: 16; OS: Linux 5.13; UI render: default; VCL: kf5 (cairo+xcb) Locale: pt-BR (pt_BR.UTF-8); UI: en-US Ubuntu package version: 1:7.3.3~rc2-0ubuntu0.21.10.1~lo1 Calc: threaded
If you drag and drop, the place where the text is dropped is not the place where the cursor is. You may get a random display of the forbidden sign.
Interested to have the exact name of processor you run.
