                OS: Mac OS X

Hi there,

I just downloaded on old version of the PC game Driver (1999) and installed and
played it through Wine. 
While playing the game, there was a flicker noticeable from the game’s
loading-screen on top of the game. It didn’t bother me, until I quit the game +
Wine and the flicker was still there.

Even when I rebooted my Macbook Pro several times, the flicker is still on the
screen.

I’m running a Version 1.8-rc4 (1.8-rc4) of WineBottler on a MacbookPro Retina
15”, mid 2014 / Yosemite 10.10.4

Any ideas on how to solve this?

Thanks in advance!

This sounds like a hardware problem, either with your screen or your GPU. 
There's nothing that Wine should be able to do to cause such a symptom.

Thanks for getting back so quickly. In the flicker, the image of the
load-screen of the game is still visible, so it did happen after playing it. 
Perhaps this gives some more info?

Even after the reboots?  Try shutting the Macbook down entirely and waiting 15
seconds before starting it up again.

Anyway, the flicker would presumably be showing you some leftover data in the
VRAM.  The precise nature of that data is not really significant.
