Workrave. Does not work at all on Wayland. But I have been using Wayland the last two years and I am glad that I made the switch. The beginning was a bit rough, but I am glad that I never have to deal with screen tearing ever again on Linux.
I've been using Linux almost exclusively (except for a stint of 6 years where my employer provided me with Macs, and even then my personal machinesiwere Linux). I've never had an NVidia, but my GPUs have ranged the rest of the options, mostly Intel and AMD. I haven't seen screen tearing since maybe the early 00s? So many Wayland advocates pick this one Xorg issue, and I haven't seen it in decades, and almost as many different computers.
Is it NVidia? Is that the common factor? That's the only thing I can think of, since I've never had an NVidia card.
