Without knowing what your module.css file, custom.css file or your config file settings are, not to mention the regions the modules occupy, I couldn’t tell you what “should or should not happen” to the display of the modules.
If the quotes module is in the upper_third region and aligned to the right then that is exactly how it should appear. Are you sure it is in the top_right region? And if so, it appears it is being allowed to expand as necessary, bringing the Mirror Stats with it.
Market Highlights would follow suit with the calendar module.
Perhaps the update has replaced your custom settings with defaults, or simply wiped them out.
Try this in custom.css for each of the modules you want to control, replacing MODULE_NAME with the name of each of the modules you want to constrain, and adjust accordingly.
.MMM-MODULE_NAME {
width: 200px;
}
