Since the "word count in status bar" feature was implemented (see Bug 34772): 1. Open new Writer document. 2. Scroll down, the cursor should become invisible. 3. Start to draw a line, don't release the mouse button quickly. Unexpected behavior: Writer brings the view back to the cursor. Similar to Bug 50386.
I confirmed that this is caused by the word counting logic focusing the view on the cursor. Will be fixed alongside 50386.
Patch was added to 50386, and I verified it fixes this as well. Let's follow up there. *** This bug has been marked as a duplicate of bug 50386 ***
