What happened?

When scrolling on the menus, there are visual artifacts, 100% reproducible here (on all recent versions of cinnamenu), on all of my laptops and desktops: bits and pieces of fonts get rendered on the top, or the right side of the cinnamenu window.

This is seen on Mint and Debian, but it is EVEN more pronounced on Arch Linux.

Please note that I have set the scrollbars to be visible at all times (in the mint prefs). I don't know if this is relevant, but I thought I should mention it.

In the image you can see a bit of it on the top of the window, that's the only screenshot I could catch with the artifact in. But in reality, it's more pronounced when scrolling up and down.

This appears to be the lower part of the application name preceding the “Dictionary” application. Nothing unusual.

I've noticed this bug for quite a while, and have reported it to @fredcw over a year ago, but I think he couldn't reproduce it. For me, it often takes the right-most column of pixels from fonts at the right edge of the menu, and moves them to the wrong location while scrolling, which ends up looking like extra dots or lines here and there along the edge of the menu. Sometimes they blink on and off. After moving the mouse or scrolling more, they sometimes disappear on their own.
