Fun fact: there was an extremely rare GIF playback/video message preview crash. It was so rare that it affected less than 0.00006 of users, happened only a few times per month, and there was no clue, except it was happening only on high-end devices. So it hadn't been yet investigated much.

In 0.20.10.958 update, this crash started happening much more often. First obvious thought that something has been broken. But turns out it was there since the very creation of the app.

It happened due to the race condition bug occured when GIF frame processed very fast (about 0.001 of a second) and quickly passed to the render pool.

With 0.20.10.958's significant frame processing speed boost, crash probability incresed accordingly, so now it is top #1 on the crash list.

TL;DR:
Sorry! Fix will come in the next update.
