Thanks, just today I decided that the current status of Meld (https://meldmerge.org/ https://meldmerge.org/) was untenable for me. It used to be a fast program, with a reasonable interface. For a long time now its interface has been "simplifed" following GNOME 3's User Interface Guidelines, and everything ended up being hidden inside a hamburger menu. But what definitely made it untenable was not the UX, but its tendency to crash and being really slow under the slightest load. I was considering contributing to the project, but honestly a better engineered alternative would be welcome. Thanks for the info (and thanks Kai Willadsen for Meld).
