Adjusting clip length on the timeline is invisible

I don't know if that wording makes much sense, but it's pretty much the problem I've got going on. If I adjust the length of any video clip in my timeline, then the length turns invisible and wont snap to anything. It makes it hard to get a clip exactly where I need it. 

I've tried resetting my preferences, reinstalling the program, changing/updating my gpu drivers, and there are no nested sequences in the project. This problem persists in other projects as well. I'm beginning to think it's a hardware issue, but I dont want to say it is because that would mean needing to buy an entirely new gpu which I do not have the money for right now. 

If anyone knows what might be causing this then please let me know what I can do to fix this. It's extremely annoying, and while it can be worked around, it drags the production time down immensely. 

Here's some photos if that helps at all.
