    What a dumb idea :l
    globally? it shouldn't be possible for random app to screw up my display, just go in your de settings and change it

    mutter doesn't implement font rendering or graphics primitives either, it's not its job.
    but i can educate you on ssd:
    first, wanting to have titile bar to be de-like, but rest of window to be de-unlike is really stupid idea not worth time of intelligent beings.
    second, if you have nothing else to do and still want your window be different from your titlebar, you don't need wayland server for it. just like you don't need wayland server to print letters or triangles. use some library, which will have plugins for different de styles of titlebars. plugins can even live in respective de repos. it doesn't exist yet? then stop posting bullshit and start doing something useful ffs

      FWIW, disabling sync-to-vblank is likely the problem here, and fullscreen unredirect (direct scanout of client buffers) should help. (The same issue should affect Xorg as well with page flipping disabled, apart from the HW cursor maybe)

      The issue is that an unthrottled client can starve the display server's GPU work, causing the compositor's frames to be delayed. Fixing this will be surprisingly tricky and require the kernel and Mesa drivers to provide a way for the compositor's work to be prioritized and finish ahead of the client's GPU work, even if the GPU has already started processing the latter.

        Fact is when X11 was exactly as old as wayland is -RIGHT NOW- xorg was already forked from xfree86 and heavily developed
        fact is, wayland is 12 years old, it started in 2008. xorg forked after license change in 2004, 17 years after x11 and 20 years after x started. fact is, you are pathetic liar

            lol. that's self-inflicted pain. you are deliberately making your game produce frames nobody can see because monitor is not fast enough. why do you do such stupid things to yourself?

              I wish Michael could test with Wayland-native games...
              Are there any Wayland-native games? And if there are any, do people actually play them?

                if it's there on your system but not on other systems then it's your fault

                  sdl is wayland-native, so any sdl game which doesn't link to x11 itself

                      Don't mind him too much, he's just stupid. He has no clue that every other display protocol except for wayland syncs output on input and that 60fps isn't a high enough input resolution. These fools think that a 50ms+ lag is ok just cause they don't notice it ...
