Windows (dialogues) and Blocks Leave Residue When Moved

This is a minor cosmetic glitch that probably isn’t very easy to fix, but I thought I’d report it anyway. For a while I’ve been noticing that, when dragging blocks or windows to the right, black lines (henceforth referred to as “residue”) can appear. Dragging the block/window back the other direction or otherwise updating that area’s display will erase said residue. Importantly, it only seems to leave residue when moving down or to the right, and the faster you move the less residue is left behind. Interestingly, at least in the example below, the residue seems to always appear in the same locations.

This bug probably has something to do with how Snap determines what parts of the screen should be updated when an object moves. I don’t believe that I have seen this issue with scrollbars, however. I am on Chrome on Windows 11 (latest version of each).

Lastly, here’s a screen capture of the bug:

Edit: Just checked and dragging blocks over the same problematic window in the screen capture produces the exact same lines.

Aha! I finally figured out what is causing this! Look at the residue in my screen capture. Now look at what was behind that window (on the right):


It is a big grid of rectangular inputs!

The residue is actually bleedthrough from the black bevel on the top and left sides of the input slots! I’ve tested and this occurs with input types any, number (number is rounded, so you have to work to get it to bleed through, but it does), and all the rings.

I created two dialog tables and dragged them over each other and couldn’t replicate that… that might be something your system is doing and might be the symptoms of a larger problem on your end. Might.

Did you put blocks with input slots beneath them?

Interesting, I just tried it again and I see it this time. Except it’s the same glitch in a different way. On my end it warped the blue heading of the box, and only above the ring if it was full.

Interesting. My bad then, there is something there. Weird that it’s different results for the same bug tho. Does your glitch vanish if you click away anywhere? (re-reads original comment, yes, yes it does)

I get residue on the blue heading if that’s what you mean…

Edit: Taking a close look at that screenshot, the black lines appear to be visible on the inputs themselves, as well as the pivots variable. This means they appear everywhere, not just on dialogues.

Chrome.v150@Windows10, :gear: \red{\text{Retina display}} , no glitch.
It seems like a display driver issue or GPU Canvas acceleration.

That’s a point. I’m using Vivaldi 8.14 (Chrome 1.50) On Windows 10, Ultrawide 32:9 Monitor, I’ll go one better and add my Nvidia 3080RTX with up to date drivers.

Chrome.v150@Windows \blue{11}, :gear: \red{\text{Retina display}}

Turning off \text{ Use graphics acceleration when available } in Chrome settings fixes the bug for me.
