I understand that nvidia support for wayland is lacking, but I know it’s possible.
For context, I was using sway 1.8 for a while (no official support for nvidia). It was working almost perfectly, only minor issues. After the update to 1.9, I get constant flickering.
I can downgrade to 1.8, but the fact that 1.8 was working tells me that it is possible for a window manager to work well for nvidia. The problem is the sway team does not want that headache (understandably so).
Are there any alternatives that work well with nvidia?
Nope, it’s a race condition for which the visible effects can appear or disappear for plenty of reasons. The only fix is explicit sync, which is being worked on for wlroots
