5 months ago Padding around the control panel could cause other issues, as the width of the control panel plus the width of the image port should be the same as that of the browser window. Also, I am still seeing scrolling in my browser - perhaps we are using different browsers (mine is Firefox).
I'd like to get to the root cause of this problem. I asked GPT4 and began to investigate, but it is getting late and I am very tired from my kayak trip. If you have a chance, please investigate these possibilities:
User When I make an MUI box the same size as the window that contains it, a scroll bar appears to the right and I can scroll it slightly (about 20 pixels). What might be the cause of this?

The appearance of an unexpected scrollbar and the ability to scroll slightly in an MUI box that is intended to be the same size as its containing window are usually due to a few common issues. Here are some points to consider that might help you resolve this:
Box Model Size Calculation:
In CSS, the size of an element (like your MUI box) is affected by its padding, border, and margin. When setting the height and width to 100% to match the container, make sure you account for any additional space that these properties might add. If the total size exceeds the container's dimensions, a scrollbar will appear.
Content Overflow:
Check if there's any content within your MUI Box that might be causing it to overflow. This could include elements with margins that push outside the bounds of the box, or even a min-height or min-width that is larger than expected.
Body Margin:
By default, the body element of a webpage has a margin. This margin can cause the overall dimensions of your content to exceed the viewport's size, leading to scrollbars. Try setting the margin of the body to 0 in your CSS:
css body {
margin: 0;
}Viewport Height:
Sometimes, using height: 100vh can cause issues because it includes the browser interface in its calculation, which might not be what you want. Try using 100% height for both your html and body tags as well as the MUI box to see if this resolves the issue:
css html, body {
height: 100%;
margin: 0;
padding: 0;
}Inspect Padding and Border:
Check if your MUI box or any parent container has padding or a border. Even a small border or padding can cause the overall dimensions to exceed the container's size. Use the box-sizing property to control this:
css *, *::before, *::after {
box-sizing: border-box; /* Includes padding and border in the element's total width and height */
}Browser Default Styles:
Be aware of any default styles applied by the browser that might not have been reset (like default padding or margins on elements).To debug this issue, you can use your browser's developer tools to inspect the MUI box and its parents. Check the computed styles tab to see the actual dimensions, padding, border, and margin applied. This should help you identify what's causing the extra space leading to the scrollbar.
