Short description of error
Blender 3.5 Image editor does not fully refresh on some zoom levels while painting

Exact steps for others to reproduce the error

Open attached file
Scribble on the top left image editor
On 3.4.1, 3.5.0 and 3.5.1, the image editor being painted doesn't seem to update the view fully, both only below that uv seam line, and 3.5.0 had more portions that aren't updated compared to 3.5.1.
Zoom in/out, it refreshes back to normal.

Note:

This only happens on some particular zoom levels, sometimes I can get a lower zoom level to produce this error too, by zooming in and out and draw, you could probably find some more zoom levels where the image update region isn't complete.
When you zoomed out to some level and it works, and then you could zoom to some other level it could fail again.

3.3.2 (correct)	3.4.1	3.5.0	3.5.1

Original description:

When zoomed in at a particular level the real time properties of the image editor stop working, In the short video i sent I am painting a texture using the Image editor window, it updates the texture on the model and the UV editor below, but the image editor window doesnt update until I either zoom in or zoom out, At first I thought it was random but then I found it can be easily replicated by simply being zoomed in at the level that I was when the bug was happening.

Can replicate, a bit tricky, but I'm able to make a file that shows more or less what's happening, updated in the report.
