rounded-window-corners VS mutter-rounded

Have you considered the extension from the same author? https://github.com/yilozt/rounded-window-corners

Thanks for your comment:) I guess you are talking about rounded-window-corners. It is great but has some minor issues, see this comment

Using this shell extension to add a 1px rounded border for all windows, which stays even for maxmized and tiled windows. This also applies to apps like Alacritty and VSCodium which don't render GNOME themed window decorations.

FYI: https://github.com/yilozt/rounded-window-corners is a new GNOME extension by the same person who made mutter-rounded.

I suggest you report it here: https://github.com/yilozt/rounded-window-corners/issues

Everything you need is under the install section

For rounded corners I've used Mutter Rounded which is basically a patched Mutter (Gnomes window manager)

Since OP doesn't answer I simply googled it and it seems like OP uses this project: https://github.com/yilozt/mutter-rounded

Good question. The dev himself has said he does use a certain patch in his build. See here.. However, I went inside the code and it appears that he first downloads the Mutter source from RPM (which does not have the performance patches, yet), builds a big "meta"-patch out of everything in the "patches" folder, and applies those changes on the downloaded mutter build. So to be safe, I downloaded 1877 and 2487 manually, and edited package.sh myself. Gnome runs significantly faster, with fewer dropped frames, especially in the overview and app menu. (1877 gave me a few quirks though so you might want to skip that.)
