I'm not sure when this started. In the forum posts when people have a signature set, there's a very faint dotted line above the signature. Problem is, all those dotted lines continue across the entire width of my monitor, over the top of the browser edges and even outside the browser window when my browser window is not maximized! I initially thought my display was going bad. But, the lines move up and down my screen when I scroll the webpage. I've never seen anything like it before. I tried to do a screencap below, but since the line is so faint it's only really visible in the photo at 100% and seems to disappear at other zoom levels and not even be visible after jpg compression. I checked the source code and I think the issue must be with this styling of this div that holds the signature.
<div class="t_sig text-muted">.

It shows up in both the latest Opera and Chrome browsers on Windows 10. I'm running my display which is a 32" LED tv (TCL brand) at 1920x1080 with 125% scaling. Maybe some incompatibility with my settings? Anyone else seeing this?

Not visible in this photo as I suspected, but this shows the signature line I'm referring to. On my screen, that line goes fully across the white page background, over the black browser side bar on the left and onto my blue desktop.

@Dave

I just did a little test and made a new blank html file using the line below which is the same style used here for the signature, and it does the same thing and goes beyond the browser window. If I change it to be 2px instead of 1px the line ends where it is supposed to within the webpage. Very strange!

<div style="border-top: 1px dotted #000000">test</div>

Is your screenshot supposed to be showing the problem? It looks normal to me in the screenshot you posted. The line is supposed to end where the "box" that the post is embedded in ends, and that's what i'm seeing in your screenshot.

It's very strange in that it will only show up in the screenshot at 100%, if I zoom in or out the extra part of the line disappears but the intentional part stays where it's supposed to be. If I crop the image and view the cropped image at 100% the extra part of the line also isn't visible. It's very weird. In my test page just making it 2px fixed the problem, but so did keeping it 1px and making it solid or dashed instead of dotted. In my Googling I only found one reference to browsers being buggy displaying 1px dotted borders.

I think it actually has more to do with Windows or the display itself, because the dotted lines in the screen capture images don't "act normally" when manipulated in an image editor either. That sounds crazy I know! So it isn't something specific to this site after all. I think I just notice it here because when I scroll through a long page with a bunch of posts that have signatures these horizontal lines are moving around on the sides of my screen, mimicking a display going bad.

I have windows and it works just fine for me. Try restarting your computer and clearing your cache.

I just thought of something stupid simple to try and took a photo of my screen with my tablet, which actually shows the lines well. So at least I don't look too crazy! This is of the test page I made using a 1px dotted border all the way around the div because I was curious if it also happened vertically, which it doesn't. Black is the browser side-bar, blue is my windows desktop.


I'll try doing a full restart on my computer to see if that does anything. I don't think it's the cache since it happens in different browsers and even with the new test webpage I created, plus the weirdness within the photo editor.

Very strange! I've never seen that kind of behaviour before. The fact that it's not showing up in the screenshot but is on your photo of the screen makes me highly suspicious of the monitor itself.

A similar issue I found on reddit seemed to indicate a monitor problem:
https://www.reddit.com/r/Monit...

Have you tried adjusting the resolution of your monitor to see if the problem disappears, or do you have a spare one you can test with?

I agree with Joshua. The artifact appearing on the screen but not present when you screenshot it absolutely points to a hardware problem, either with the display or the graphics card. I looked at the TCL TV on Amazon and a lot of the reviews mention lines on the screen.

That reddit post does look like the same issue. A restart had no effect, nor did changing my Windows scaling % down to 100% or up to 150%. Lowering my resolution did make it go away, but that may be because it just makes everything pretty blurry! 1920x1080 is the displays native resolution, so it looks best there. The lines do show up in a screenshot... sort of. I think just displaying that intentionally dotted 1px line at the native resolution even in the screenshot causes the display to try to continue the line across the whole screen. But, once you look at the screenshot scaled differently or save it as a jpg it blurs it just enough so that my display doesn't react that way anymore.

There also seems to be some kind of threshold of number of dotted pixels in a line that triggers it. If I open the screenshot image in the Windows Paint program and cut and paste elsewhere a small section of the intentional dotted lines, the error caused lines won't appear next to the newly pasted section. But if I cut and paste a large enough section of the intentional dotted lines, the error caused ones disappear from the original area and are now created next to the new pasted object elsewhere. These new lines also across the whole screen just like the original. Very odd behavior. I might try to test it one day hooked up to someone's laptop to see if it acts any differently.

I've been using 32" tvs with this computer for many years because I don't usually play games on it where I'd need a more responsive display. Overall it works pretty well for my needs and being only $130, but I guess this is one of the tradeoffs! My computer is also ten years old with onboard graphics, so yeah... I'm pretty cheap! Although, it seems like some people with problems like this are using proper computer monitors. Thanks so much for looking into it and the insight guys. My Google-fu wasn't working apparently.
