This post is in part a response to an aspect of Nate’s post “Does Wayland really break everything?“, but also my reflection on discussing Wayland protocol additions, a unique pleasure that I have been involved with for the past months.
Before I start I want to make a few things clear: The Linux desktop will be moving to Wayland – this is a fact at this point (and has been for a while), sticking to X11 makes no sense for future projects.
By switching to Wayland compositors, we are already forcing a lot of porting work onto toolkit developers and application developers. This is annoying, but just work that has to be done. It becomes frustrating though if Wayland provides toolkits with absolutely no way to reach their goal in any reasonable way.
Many missing bits or altered behavior are just papercuts, but those add up. And if users will have a worse experience, this will translate to more support work, or people not wanting to use the software on the respective platform.
What’s missing?
- Window positioning
- Window position restoration
- Window icons
- Limited window abilities requiring specialized protocols
- Automated GUI testing / accessibility / automation
I spent probably way too much time looking into how to get applications cross-platform and running on Linux, often talking to vendors (FLOSS and proprietary) as well. Wayland limitations aren’t the biggest issue by far, but they do start to come come up now, especially in the scientific space with Ubuntu having switched to Wayland by default. For application authors there is often no way to address these issues.
Everything works fine for me on AMD system with Pop. These types of posts are usually from folks with systems that have poor compatibility. That's not Wayland's fault.
Meanwhile, after updating my nvidia driver to 545.x, I can no longer play games on Wayland due to heavy flickering. Ah well, at least I can still switch to X11 for gaming. But Nvidia really drag their asses when it comes to Wayland (or linux gaming in general) support.
I experienced some bugs while gaming on Wayland even with an amd card. My workaround was switching back to X11 for gaming. That said, I didn't even notice that I was using Wayland by default for a long time until Firefox completely switched to Wayland I experienced some heavy artifacts in Firefox (only if it's full screen on my second monitor, but that's a daily thing). And because of that, switching back to X11 isn't a workaround anymore, unfortunately its my new default.
