[Linux] consistent crash when quickly browsing big files

by pangwolin (Posted Sun Oct 16, 2016 9:57 pm)
XnViewMP 0.82 (x86_64) is consistently crashing when browsing (in View mode) a bunch of big jpeg files and pressing the ESC key while it's still reading files (from its queue, on the fly).

Here is what I do to reproduce it:
* open a directory with a bunch of files
* start rolling mouse wheel very fast to have a bunch of files queued for rendering
* press ESC while it's still stepping forward to next files

Result: XnView hangs, eats > 100% of CPU, can't recover have to kill it.

It seems to happen while a jpeg file to be displayed is still rendered as the (progressive?) blurry preview (in View mode), and pressing ESC ungracefully interrupts its pipeline, which leads to an infinite loop somewhere (?).

Here below is the last few lines from terminal output.
