[5.3.1] Some UI visual bugs that I don't know how to explain

Taken from this thread, where I showed some examples of UI visual bugs.

and

The first one may be an Alienware laptop graphics card issue, and it may have been on my end (could confirm by testing on an Alienware desktop), so there’s that.

But the second one is more common among multiple Alienware hardware, be it the laptop or the desktop. I don’t think it’s on my end, but I don’t have different hardware to test on to confirm this. (Our school has a contract with Dell, and all we have are Alienware stuffs.)

For the second one, one member mentioned how it could be 2 UI elements overlapping with each other, creating this. The red X would be the overlapping issue, but would it affect the UI elements turning to pink?

The pink looks like a shader error. Are you using a custom material or shader?

No custom shaders or anything. It’s just the Canvas UI. I’m pretty well known that I am not a shaders or graphics type of developer.
