#13914: SCI: PQ2: Pixel Artifacts after clicking on top menu bar
---------------------------+-------------------------
Reporter:  antoniou79      |      Owner:  (none)
    Type:  defect          |     Status:  new
Priority:  normal          |  Component:  Engine: SCI
 Version:                  |   Keywords:
    Game:  Police Quest 2  |
---------------------------+-------------------------
 This is on 2.6.1 stable and also on current 2.7.0git from master HEAD on
 Windows 10 x64, with the GOG version of the game. OpenGL graphics mode.

 Step to reproduce:
 1. Start the game
 2. In the first screen (Sony is in his car) move the mouse cursor to the
 top of the screen on the menu/Score bar and click on it -- it doesn't
 matter if you select a menu option or not.

 What happens:
 - Pixel artifacts appear on the top left of the screen (see screenshot),
 overlapping with the menu/Score bar. These pixel artifacts look like they
 belong to the next screen (when Sony is outside his car, in the Police HQ
 parking lot), but they still overlap with the top menu there.

 What should happen:
 - These pixel artifacts should not appear, at least not while inside the
 car.
 On DosBox (used by default when running the game from the GOG launcher),
 there are not artifacts there.

 I have not checked whether this issue persists in other screens of the
 game.

 I tried the default settings for the game and also the "use RGB rendering"
 but the issue persists.
