UI performance is bad

[swiftech]

This is a good free tool for comparing on Mac, but the performance of UI is bad, especially when you scroll the directory tree or the text view, it goes very slow . This is MacBook Pro (15-inch, 2019), not any old laptop of MacBook, I guess there is something wrong with the build, maybe it is easy to fix after some profiling.

Meld version: 3.21.0.osx1
OSX version is Catalina 10.15.3

The problem is with gtk macOS port (quartz). I had to re-enable macOS decoration in the new release to overcome that issue. Hopefully gtk 4.0 with vlukan backend would allow me to revert to gtk decoration when it comes out.

Please try the new release.

Great job! I have tried the new release, it's performance is a little better than last release, but still slow. Hope next release will be better, thanks.

I'm running Meld 3.21.0.osx2 on Catalina 10.15.6 and would say that UI feels still a little sluggish, would be greatly appreciated if this could be improved.
