Bug report (I searched for similar issues and did not find one)

Current behavior

If my app navigates to a new page with gridsplitter controls sometimes the cursor disappears. The cursor only appears if hovering over a gridsplitter control.

Expected behavior

The cursor should be visible.

Minimal reproduction of the problem with instructions

Create a page with 2 gridsplitter controls, then from the main page navigate back and forth a few times to the page with the gridsplitters. Eventually, the cursor disappears.

@shweaver-MSFT, could you look at this as part of #2013?

[shweaver-MSFT]

Ya, no problem. I'll try out the repro and see what's going on.

@nmetulev, I can't seem to repro the issue. I created an app with 2 pages. MainPage has a button that navigates to the OtherPage. OtherPage has 2 GridSplitters and a few buttons to navigate back to Main. I tried navigating back/forth dozens of times with no issue. Cursor is always visible and changes as expected when hovering/manipulating the GridSplitter.

Test app is here: https://github.com/shweaver-MSFT/GridSplitterCursorTest

@fatcatz888, would you mind trying out the test app to compare with the issue you are seeing? Or do you have an encapsulated repro I could try?

[fatcatz888]

I'll give it a test.

Thanks

I just hit this too, but couldn't repro again when I redid what I thought I did. We can clean-up the GridSplitter to use our Mouse Cursor extensions, that may help maybe. I can look at it after Build as I should try and finish and add in my ContentSizer sister control.

Thanks for the update. Since you can reproduce the bug too now I won't be pulling my hair out trying to get the test app to make the cursor disappear!

I just know it is completely random.

What's the current status of this issue?

[lucaasrojas]

I tried to replicate the issue using the v2.2 and v3.0 without success. I also tried moving the back button outside of the grid, but I couldn't replicate the issue.

@michael-hawker Did you have a chance to look at this?

[michael-hawker]

@kbrons @shweaver-MSFT I think I hit this again. I was on a Surface Book, so I wonder if it's HW dependent?
