animated image embedding (Imgur) prevents screensaver/screen blanking on MacOS while irccloud-desktop is running
Viqsi opened this issue · comments
If ever a link to an Imgur animated image is posted in IRCCloud using the desktop interface, it prevents screen blanking. The following messages repeatedly appear in the MacOS console every time the video loops:

They repeat every time the image loops. This occurs whether the image is currently visible in the viewport or not. If one "closes" the Imgur "window" (by clicking on the X in the upper-left corner and thus getting rid of the embed), these messages stop, and the screensaver is able to come on.
I've confirmed this with Imgur; other services might also be affected (haven't had the opportunity to test them). It also appears to occur if one is using irccloud.com via one's web browser.
