Ah, was hard to see what you were referencing at first. Specifically, the different types of visual elements that you can select to draw on the page are going missing. Definitely understand how that can be frustrating.
While it may not be the issue, what browser are you using? (Looks like Chrome?). It may be that you have a plugin that’s causing some issues.
Try using Firefox for a bit and see if the issue reoccurs. If it’s persistent across browsers, I suggest filing a bug report.
