Only half of your Gimp Toolbox showing up?

If only half of your GIMP toolbox is showing, it may be due to a display issue or the toolbox window being minimized or placed off-screen. Try resetting the window layout by going to "Windows" > "Dockable Dialogs" and selecting "Toolbox." You can also check for updates or reinstall GIMP if the problem persists. Additionally, ensure that your graphics drivers are up to date, as these can affect application displays.
