Hi,
Thanks for both of your feedback. Let me just clarify that ROOT moves to the web-based graphics not out of boredom: we know that the old, platform-specific graphics backends are not sustainable. Windows uses some 30 years old library, we would need to rewrite much of the macOS GUI / graphics code having to higher a macOS developer, and Linux is migrating to Wayland. The old GUI / graphics backend forces us to deal with “wonderful” issues such as Can't open TBrowser locally after upgrading macos “Apple M2 14.0 (23A344)” · Issue #13834 · root-project/root · GitHub
Especially as a power-user you know what to do when you find a problem: open a bug report with a screen shot of what you see, an indication of the problem and the code you use to generate this problem. That way we can fix it, for everyone. Sergey has done a fantastic job in fixing super quickly everything that came his way.
We have received some reports of problems with the web-based graphics over the last few months - not many, but at a consistent (low) rate that we prefer to still release with the old graphics system being the default for the v6.30 release. master and TBrowser will continue to use the new, web-based one. We expect to switch the default graphics backend to the web-based one for v6.32. Please help us fix everything you see by then, by reporting issues today!
Cheers, Axel
