Various UI Bugs

I've been having very intermittent UI bugs that I will do my best to describe since I have yet to figure out how to take snapshots or videos of the in-game screen. Most of the time, these issues all occur within the same game. If I see one of these bugs, it is very likely I will see the others throughout the course of the match.

1. Champions on scoreboard all stacked on first row. This one is the one that happens most frequently and is the hardest to deal with. What happens is that, for the entirety of the match, from the moment the game starts, when I open the Scoreboard, all of the champs from both teams are stacked up on the first row. [Clarification: All 5 champs from blue side are in the first blue side slot, and all of the champs from the red side are in the first red slide slot.] When I attempt to drag any character to a new row, they snap back to the first position, but one of the other champs is now the one shown on the top of the stack. This effectively allows me to cycle between the first two champs on either team by dragging them to a lower slot, but they always stack back on top of one another. This leaves me with no way to look to see what my lane opponents are building and so no way to counter.

2. Health bar stuck at 0. This one occurs slightly less frequently. I actually haven't seen this one in a little while, but I only get bug #1 every 25 games or so. After my first death, the health bar in the bottom of the screen (the full health bar) will be stuck at 0 upon revival. It shows as completely empty and in all black, flashes every time I take damage no matter my actual health, and always shows 0/[FULL HEALTH]. This does not affect the actual amount of health I have, and the health bar above my actual champion shows normally for myself as well as my enemies.

3. Champion icons above minimap stacked or missing. This one happens almost invariably if I see bug #1. There are numerous weird things that start happening with the champion icons above the minimap. Sometimes some are missing. Sometimes they are misaligned with each other (i.e., blue team will only have 2 icons showing and red team will have 3, and they are both set to equally space the icons, so it looks like they're trying to form a pyramid, stacking the 2 icons in the space above and between the 3). Sometimes they show champions permanently at level 0. And sometimes I'll click one to signal my team "[Champion] - Revives in X" or "[Champion] - Alive" and it will give one of the missing champion's information (which is what leads me to believe that they too are stacked).

Hopefully this post is detailed enough to give some idea of where the problem might lie. I saw one other post with a potential preventative measure for bug #1, but I'm hoping to get these more firmly resolved. If there is any way I can continue to help this get fixed, or if someone could let me know how to properly capture game snapshots or footage, let me know.
