mpv fixed the issue in their master, not sure if the same thing can be applied in imv. I tried naively to find some similar portion of the code in imv, but could not find anything relevant

https://github.com/mpv-player/mpv/commit/cd3b4edea06dec659d9676f2649cc1b1be2e8565

continuing my investigation, I can get the master of imv to work on output with scale > 1 with this patch

diff --git a/src/wl_window.c b/src/wl_window.c
index 5efa42f..77b02f2 100644
--- a/src/wl_window.c
+++ b/src/wl_window.c
@@ -488,7 +488,7 @@ static void output_scale(void *data, struct wl_output *wl_output, int32_t factor

   struct output_data *output_data = wl_output_get_user_data(wl_output);
-  output_data->pending_scale = factor;
+  output_data->pending_scale = 1;
 }

This is obviously completely ugly and definitely not the fix, but it does fix the issue partially (the image shows but it's blurry)

Seeing the same issue. Should be noted that the window renders for an instant, and immediately closes. imv-wayland continue running with very high CPU usage in the background.

Are you all seeing these additional symptoms too?

I haven't checked the cpu usage, but I see the same symptoms otherwise, yeah

Above patch works for me. Thanks!

After recently upgrading to wlroots 0.16.1 I get the this error as well:

wl_surface@9: error 2: Buffer size (956x1055) is not divisible by scale (2)

Running on archlinux with imv 4.3.1-7 Using sway with scale 2 setting

Getting the same error as @nittens, also on wlroots 0.16.1-2. Works in even dimensions, though fails immediately on odd dimensions with imv-wayland taking up 100% CPU.

The problem only occurs when opening it. If imv is first opened in even dimensions, then resized to odd ones, it doesn't crash

Same for me.

Above patch works for me. Many thanks!
