They don't have a native Wayland solution yet (only third party compositors). Gtk4 actually removes some X11 functionality. It's a terrible toolkit, only useful for mobile UIs.\n\n\n>\n> I know I stress about the way Linux is a lot (and I'm sure it can annoy fans of it)... but I feel when we ask those kind of questions about how to support the platform going forward in the next 5 to 10 years that typically have straight answers on Windows or Mac, they often get answered on Linux with discussions about internal distro politics, various developer's ideals, personal opinions, and sometimes even wishful thinking more than sound technical guidance or a concrete plan that can be trusted in a lot of cases.\n\nConcerning toolkit the answer is easy. Gtk3 all the way in the next 5 to 10 years. When Qt 7 is released then Qt 6 becomes attractive (as a stable target). Gtk4 isn't a realistic alternative IMO.\nI don't think you have to worry about Wayland. XWayland will always be around even though Wayland users might not want to use it.\n\n\n>\n> Yeah, we'd probably have to be conservative as far as what we targeted if we go that route, because presumably stuff compiled against older Qt 6 would work on newer Qt 6, but not the other way around. I have to admit, following a system-wide theme is not something I really thought about much because I figured most people would be using custom themes with Pale Moon anyway, and that we wouldn't necessarily have inherited the Firefox-era concerns about matching system theme so closely (despite that being a hard mission on Linux) given Pale Moon's design goals. This is sounding like we may actually want to take that more seriously, but I'm really just trying to gather notes here.\n\nI don't think Pale Moon themes are that popular among Linux users because gtk adopts the system-wide gtk theme. The same thing is true for Qt. On Linux, Chromium-based browsers enabled 2 front-ends (gtk3 + Qt). When gtk3 is dead (will take a while) then the Qt front-end might be the only one left. Now, when thinking about this it actually seems that Chrome blends with system-wide Qt theme despite being compiled against a static Qt version. I have to test this some more when on Linux.\n\n* * *",
