For quite a while I had a problem on TBrowse grids where the screen background would turn black. This problem only came up on new versions of Windows 10, and only on some workstations (specifically Dell). I finally found a resolution and would like to share it.
Our tbrowse grids far left column had a bitmap which we would toggle from having a bitmap, to no bitmap.
When we toggled to no bitmap we just set the bitmap to nil.
Worked fine on Windows 7, and some workstations on Windows 10.
This seemed to be the problem. I need to create a blank bitmap and problem went away.
So instead of setting it to nil we set to a blank bitmap (or whatever color the background was).
Hopefully this helps somebody.
Thanks,
