What compositor are you using? That should be fine, or you'll just be able to commit when your timer to update the clock fires after rendering new content. |

Could you test in another compositor (sway can be run windowed) |

I was able to get the frames to update without any user intervention! However, not using the let guard = event_queue.prepare_read().unwrap();
let fd = Generic::new(
guard.connection_fd().as_raw_fd(),
Interest::READ,
Mode::Level,
);
drop(guard);
let event_queue = Rc::new(RefCell::new(event_queue));
let event_queue_loop = Rc::clone(&event_queue);
event_loop
.handle()
.insert_source(fd, move |_, _, data| {
if event_queue_loop
.borrow_mut()
.blocking_dispatch(data)
.is_err()
{
panic!("display_dispatch");
}
Ok(calloop::PostAction::Continue)
})
.unwrap();
{
let mut event_queue = event_queue.borrow_mut();
event_queue.roundtrip(&mut simple_layer).unwrap();
event_queue.flush().unwrap();
}

Hmm that is odd @elinorbgr do you have an ideas why this could be happening? I'd probably avoid doing that above specifically since it seemed to cause the Nvidia driver to have some issues when talking to Wayland. |

Right now, I'm trying to make a status bar using the
wlrlayer shell protocol. I don't want to ask for a new frame on every frame because my bar spends most of it's time waiting forcalloopevents, so every time the status text needs to change in the bar, I callUnfortunately, I only get the frame notification when I hover the mouse over the bar, then it gets the next frame notification(s). Is there a way that I can initialize new frames without having to hover my mouse over the layer surface or continuously ask for new frames?
The code I'm using is basically exactly the same as the
simple_layer.rsexample (but with thelayer.wl_surface().frame()calls in thedrawfunction commented out, and theWaylandSourcebeing used instead of theloop).Thanks in advance for your help, I swear I tried to find this out on my own but I couldn't find any docs or anything online or anything in the codebases I have on my system on how to do this.
