I just ran Neovim in terminal and was used to Neovide, so I thought it was choppy.
Intel HD 630.
There is, however, a 2D game - which I am not going to disclose the name of - that’s pretty broken. (It uses Adobe Flash as an engine)
Also the steam client doesn’t maximize properly with tiling but I am sure that’s reported.
I have been daily driving Cosmic for a week now; it caused me Arch-syndrome, everyday I run sudo apt update hoping to get some polish to the desktop.
Edit: there’s more…
Neovide’s transparency is completely broken, and shows a blank, though not a pitch black, color and screenshotting it results in seeing the text with a checkered background. (In the resulting screenshot only) (Running on Proton 8.0-5)
clipboard=unnamed plus, the setting supposed to unify Neovim’s clipboard and system’s, doesn’t work. clipboard: error : Error: target STRING not available
I also was unable to transfer a file to my phone using Cosmic Files, but Nemo worked, though I read that’s fixed in some Blog.
Edit II: I just discovered popdev:master it seems to be a general unstable branch instead of just Cosmic things, but I took the risk and added it, I just have to remember to remove it once 24.04’s released
