Newly opened image not visible in image window when rulers and scrollbars are hidden
This started happening after updating GIMP-2.10 and 2.99 yesterday, after not updating for perhaps a couple of months, on Debian Sid updated within the last three days. It affects both versions of GIMP. Start GIMP. Make sure GIMP opens in Multi-Window Mode. If not, change to Multi-Window Mode and restart GIMP. Then create a new image or open an existing image. Very often the newly created or opened image isn't visible in the image window.
Resizing the image window makes the image appear.
