Objects or areas vanishing and reappearing at random

[Des Cuddlebat]

It often happens, when I select a curve or shape, or deselect it, or change zoom or scroll, that couple objects suddenly stop being rendered. They reappear whenever I do anything I mentioned again, sometimes with other objects disappearing. When I tried to study this issue a little, it happened that sometimes it weren't objects, just like a rectangular area became white.

Version: Inkscape 0.92.0 r15299, 64-bit, installed with .exe file
OS: Windows 10 64-bit
Affected files: Any, the file I noticed it in was created with 0.91 but it happens even in a freshly created one.
How often: Couple times every minute

I have not seen a report for this, and considering how often it happens it would be weird if nobody had noticed it yet... Dunno what went wrong >.<

I have the same problem.

OS: Windows 8.1 64-bit
Inkscape 0.92.1 installed with .exe

I did not have this issue in 0.91.

It seems to me that it happens mainly when I edit something and especially if I undo or redo a change.
Since it's happening several times per minute it completely breaks the workflow.

could you attach the original svg file, for testing purposes?

This affects all files as far as I can tell. I've had to go back to 0.91 for now to be able to work but I can try to re-install 0.92 later to check if there are any files that don't suffer from this bug.

Anything that was un-rendered was re-rendered if I took any action, such as zooming. Also, if I did anything to cover an un-rendered object (such as panning) it would come back to whatever extent it had been obscured. This gives me the gut feeling (as a complete layman) that it's an issue with how this version of inkscape relays information to the driver or some such thing since it's a purely graphical glitch.

Ok, I re-installed 0.92.1 to check again.
The news is that, at least from what I can tell right now, the vanishing only happens upon undoing an action.

I just drew a few lines in a new document (to be sure that it's not a memory issue with the far larger documents I encountered this in).
Sometimes when undoing an action, all lines vanish from sight. This happens after only a few iterations.
I'm quite positive there's nothing special about this file, and that this is evidence that the behavior affects any file, but I'm attaching it anyway.
