Description

I managed to convince DrRacket to issue the following warning to stderr.

2022-11-06 18:25:05.521 DrRacket[45378:94387379] Warning: Window move completed without beginning

I suspect this is related to a MacOS software bug, since I found a workaround to a similar warning in some Tk source (https://core.tcl-lang.org/tk/info/9726c0e9a5004ed3). When I saw this, I opened many racket files at once in DrRacket from the terminal, and at the time I was seeing multiple copies (3?) of the DrRacket icon in the Dock. I killed (via command Q) the ones that seemed irrelevant to the task at hand.

Research direction

The report names no DrRacket file, test, or entry point. Start by reproducing the warning on macOS Monterey or later while opening many Racket files from a terminal, then compare the behavior with the linked Tk workaround. Done means identifying a reproducible cause and documenting or validating a project-appropriate fix.
