img2img editor starts to malfunction after several cycles of use

Describe the bug

After several cycles of refining an attempt at inpainting, the drawing canvas starts to show the wrong image.

To Reproduce

I haven't pinned down the exact sequence of events, but some blend of clicking "Use these settings", "Make ... images", "Draw", and "Inpaint" repeatedly (i.e. experimenting with refining an inpainting prompt, both the mask and any sketched-in hints at the desired result) will cause the drawing canvas to malfunction.

While I've always seen the correct image data saved, what's displayed to the user will be one of two states:

1. It will just display the wrong image persistently. The only solution to this is to reload the tab and accept the hassle of prematurely starting a new autosaved subfolder.
2. It will rapidly switch between images as the cursor is dragged around.

The images chosen from appear to be a mix of the random recent images. (eg. It might show a previous prompt's img2img image or it might present an old inpainting mask as the base image when you try to inpaint.)

In the latter case (the one that feels like some kind of analogue to a backbuffer swapping bug), it can sometimes be worked around by switching to the Erase tool and scrubbing around a part of the canvas where you know there's nothing to erase until it stabilizes, then switching to the Draw tool and trying to draw as normal. Repeat until effective if necessary.

Whether it's just the background layer or also the inpainting mask that's drawing from the wrong source can also vary.

Oh, one detail that was lost in revising before posting: I've been using Easy Diffusion for quite a while and this bug crept in some time during the hiatus I took within the last few months.
