Description Storm Engineer 2019-08-02 12:26:54 UTC

I was trying to undo some free transforms, when suddenly my layer content disappeared, and the canvas stopped updating, and nothing I tried (eg. toggling layers on/off) helped.

I tried to scribble on the layer and that appeared, but undoing that the layer returned to empty

I went back in the undo history several steps before the scribble - the canvas was still not updating but I hoped it is only visual. I saw my previous drawing in the undo history thumbnails.

I saved and restarted Krita.

Upon opening my file, the layer in question contained nothing but the scribble that I supposedly undo-d. All previous content were lost permanently.

I don't know how to reproduce.

Please update: cec1505 isn't that old, but Dmitry fixed a bunch of issues in the transform tool.
