Hello,
Delphi 10.2.3.
A strange drawing artifact appears at the top. Much searching for the cause, no joy.
Example project is attached.
IB2.zip (87.7 KB)
Here is the window before doing anything that forces an update.
After update:
See the black bar at the top?
Using the mouse slowly decrease the height of the window and the black bar disappears.
Changing the window height, slowly, you can see the black bar appear/disappear.
Ideas?
Thanks,
Mark
