Rendering is aliased

[acerspyro]

Not sure if this is just a GNOME issue, but the corners aren't anti-aliased when rendered.

It doesn't even do that anymore with a new install. Now it's just chopped at a 45 degree angle

Yeah, I noticed that as well.
It's not that bad but it's still noticeable.

This issue can be easy fixed by tweaking corners SVG files. The issue is that canvas size specified in those SVG files is too large (256x256 pixels) and this results in aliasing when rendered bitmaps of corners images get downscaled to user defined corner rounding size. In my case the following values tweaks works the best and gives nice smooth rendered corners:

In all four SVG files:

• replace all "256" values by "8"
• replace all "512" values by "16"

This also can be done on installed extension. Just edit SVG files in ~/.local/share/gnome-shell/extensions/Rounded_Corners@lennart-k/corners
Changes will take effect right after files changed.
