I'm encountering a misbehaviour in the image viewer.

When I open an image from any chat, the image viewer shows the previously
opened image instead, whatever chat it was from. After that, sometimes it
switches to the correct image in less then one second, other times it takes
several seconds, other times I have to close the image and open it again.

If I have not opened any image after the last time I launched Telegram Desktop,
the correct image is showed.

Please ask for any information you need.

Cheers,
