disappearing and appearing brush stroke

I had this issue just now and I had to mess with my actual GPU settings, and completely disable the weaker of the GPUs, that being the factory one. I have Nvidia 1050 so when I enabled that, for the computer to use that primarily, it worked fine again. I have a feeling it has to do with the last Windows Update.

Is this a windows surface pro, might be an issue with the surface pro settings as we have had many issues with that computer  on the forums.

Looks like your smoothing is set to 0%, but please make sure is 0% and these are unchecked.

Uncheck all brush settings, whenever your brush is working unexpectedly

We've seen other posts with what sounds like a similar problem, but I can't remember seeing a definitive answer.

One idea is that it is caused by having Gestures enabled, and your hand resting on the screen while painting.  It looked like it was only half the stroke disappeared, and if was due to Gestures, it would completely undo the last action.

Another idea is that it could be the brush Mode, but that would need a delay between laying the stroke, and it viewing according to its mode.  I have not encountered that.

This is the last thread I remember on the subject.  It's two weeks old, so might be related to a recent update.  No solution was found as far as I can see

Brush strokes disappear and reappear

Could be as trivial as a refresh issue with your graphics hardware. Check the drivers and settings. Also check your history panel. Dynamic brushes can clog up the panel quickly and cause refresh delays, especially if your underlying harddrive setup isn't particularly fast. Limit the number of steps or turn it off entirely.
