[ ^ video of the bug ]
Hi,
Here is a bug very damaging : tiles crashes on the canvas and content of the
layer is lost. One of the most frustrating bug of 2016 while drawing/painting
with 2.9.11. It's a hard bug to find or trigger, and also very hard to propose
a way to reproduce it. I try to hunt this one since january because I
experience it on weekly basis. Today I started to record a video, and the bug
happens. ( a 5 minute video in attachment ). So, I'm filling this bug with this
video because maybe the video will give you hint of what really happen, and
maybe how to prevent it. I totally understand if this bug keep a long time in
unconfirmed, or in a 'wait' status. Thank you for your time studying this one.

---------------------------------------------------------------
(Note: I'm using 'Temporary save tweaks to preset' in the brush editor)
* (3:00min) I switch from a a pixelbrush engine preset ( temporary saved with
'Eraser' blending mode ) to a Deform engine preset, to tweak proportion. The
Deform-engine preset use the 'Copy' blending mode.
* (3:32min) I press 'M' I enter in mirror view mode.
* (3:34min) I switch back to my pixelbrush engine preset, and press 'E' because
this one was in erase mode. Note how the blending mode is not restored to
'Normal' but change to 'Copy' ( *BUG*) of course, I start to notice it while
painting. I try to press 'E' but the eraser switch is blocked.
* (3:54min) I manually go to the blending mode drop-down list in the toolbar,
to switch back my tool to 'Normal' blending mode. I paint, but the result is
still a 'Copy' blending mode.
* (4:12min) I'm zooming in and out, to try to solve this issue by refreshing
the canvas zoom. No success.
* (4:17min) I'll switch visibility of layer on/off ; it will trigger the major
bug here. When visibility is back , half of the tiles crashed ; the drawing is
good to go to trash.
* (4:23min and after) A series of attempt to recover the drawing, duplicating,
putting the layer inside a group, etc... No : the datas are lost.
