+This issue occurs at least with the ITX motherboard //ITX-N100-2L V1.31//. A special feature of this board is that, in addition to a VGA output (reported as "DP-1") and an HDMI output ("HDMI-1"), it also includes an internal display connector (LVDS, reported as "eDP-1"). There is also a variant with a DisplayPort instead of VGA, which explains why Batocera refers to the VGA output as "DP-1".
+It is likely that similar motherboards are also affected. Some mini PCs on the Asian market use the //ITX-N100-2L// or similar boards with such an internal LVDS connector.</WRAP>
+A typical symptom of this issue is screen tearing in games as well as in EmulationStation, even when VSYNC is enabled (which is the default setting). This is particularly noticeable in the intro/attract mode of //Marvel vs. Capcom 2//, but it should also be clearly visible in other fast side-scrolling games.
+To fix the problem, go to EmulationStation’s **SYSTEM SETTINGS**, then under **MULTISCREENS**, set the video output to **NONE**.
+If graphical issues still occur afterward, check whether **PERFORMANCE** or similar is enabled under **DECORATIONS** / **HUD** and disable it.
+<WRAP center round tip>
+Disabling eDP-1 at least on the ITX-N100-2L causes graphical glitches during game start animations (e.g., **GAME LAUNCH TRANSITIONS** like **FADE**). The only known workaround as of version v41 is to go to **USER INTERFACE SETTINGS** → **GAME LAUNCH TRANSITION** and set it to **INSTANT**.</WRAP>
