Rounded corners are missing (square indents instead)

when placing the dock left and right of the screen
the active area is not disformed

this was happening on yaru dark, switched to yaru as a test

now it does not happen anymore on neither

I can't seem to reproduce the issue yet.

can we consider that one as resolved if it's working now?

The bug looks like a missing texture. Rounded rectangles are made up of 5 solid rectangles plus 4 rounded corner textures. I have only seen the rounded corners go missing in:

 * Nvidia bug 1876632
 * Upstream bug https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4477 (fixed in gnome-shell 42.rc)

Maybe it's the second one because gnome-shell 42~beta-1ubuntu2 was missing that fix. The fix should already be released in gnome-shell 42.0.

i did not see this bug again (on intel graphics)

Reopened due to duplicates.

I'm having the same issue, but for me sometimes de rounded corners also disappear causing a very odd background around the icon.

I guess one possible cause of this issue is nvidia bug 1876632 so please check that first.

I have this issue on an Intel graphic laptop

The problem also occurs for me on laptop with Intel Graphics. I use the dark theme.

It seems to be something when loading the session, because after locking and unlocking the screen, it goes back to normal.

It looks like we're caching an incomplete rendering (missing the corner textures), but only sometimes. From what I recall this code is entirely in gnome-shell (I think I touched it last) but I don't know why only ubuntu-dock would have the bug.

I sometimes encounter this bug when logging into a new Wayland session. It doesn't appear to happen every time though. I don't know why this is the case. I have tested it on multiple X.org sessions, but I have been unable to replicate it there. I don't know if X does not have the issue, or if I am just "lucky" here.
