Quitting GLTeapot through the file menu leaves an image on the screen

[HaikuReactOSTrac]

When I quit GLTeapot through the file menu, the title tab and the window border disappear, but a motionless teapot remains, which can be erased by moving the cursor over it. I Tested hrev42637, but this also occurs on R1/Alpha3.

this does not occur when the GLTeapot window is closed with the close button on the window tab.

A duplicate of #6614 indeed, nice catch Disreali.

Replying to HaikuReactOSTrac:

this does not occur when the GLTeapot window is closed with the close button on the window tab.

That is not a concern. The issue is that the rendering area is detached from the window, which is the issue ticket:6614 already reported.
