Hello SimaKyr, could you please tell us what theme you're using? This white line looks like a border of some kind. Can you also see a white line at the top when you disable dash to panel? Thanks!

@charlesg99 When i disable dash to panel, i don't see this line

[goosesima]

i use PopOS, default theme what i got when i install

[charlesg99]

I installed PopOs theme and I see no such line. Do you see this line if you change wallpapers? Do you have other installed extensions that could cause this? Thanks!

You might be able to determine if the gap is an element by using Looking Glass (Alt-F2 and then type in lg) and seeing if you can select it with the dropper tool in the top left.

any solution to this, I am experiencing the same issue. I got a new computer from system76 with pop, installed dash-to-panel and now a white line appears on top. If I disable the extension, which re-enables the top bar, the line disappears. It feels like the issue is that the top bar is not being hidden perfectly?

@thinkloop please follow the steps in my preceding post and report back. Thanks!

@jderose9 I tried that but alt+f12 doesn't seem to do anything for me. It seems to be related to the theme. If in gnome tweak I change themes from "pop" to "awaita (default)" is goes away. Also if I make a selection marquee on the desktop that goes over the line it covers the portions it is over.

@thinkloop It's F-2 rather than F12.

There shouldn't be a panel at the top when you see a panel at the bottom as the panel is actually moved rather than re-created. Only if you have multiple monitors would any additional panels be drawn (you could try to disable "Display panels on all monitors" to rule out possibility of a secondary panel being drawn on the main display).

At this point, though, it sort of sounds like to me that the pop theme is creating the gap at the top of the screen, and you can't see it normally as the top panel is over top of it.

Thanks for helping to diagnose!

I'm going to close this as I believe it needs to be reported to the PopOS theme creators. Feel free to report back if you find otherwise! Thank you.

Can confirm that this issue is specific to the pop gtk theme, specifically when using a second monitor/when there is nothing at the top of the screen (so this isn't visible on a single monitor by default but becomes visible when using dash to panel)
