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.
Hm, odd. I'm playing Rocket League with Proton fine with no flickering. I'm using KDE. Proton 8 shouldn't have any of the Wine Wayland stuff yet...
And yeah, I had a massive flickering problem for my entire monitor on 535, but the problem is now localized to XWayland programs on 545, so it's an improvement for me.
In my case, if the game framerate > monitor framerate, no issue with proton under xwayland. But if the game framerate < monitor framerate, it'll flicker or stutter heavily.
New vegas is smooth, while rdr2 would flicker and stutter.
I've been getting stutters for a long time. I've kind of come to accept it as part of the Proton / NVIDIA experience :) Though the stuttering has finally receded to almost nothing since running KDE Wayland. It's actually a lot worse on X11 for me.
