Same thing on my old laptop with Nvidia GT 540M, I'll add driver output next time I use it. |

Version of OpenTTD
Current master (since OpenGL was merged)
Expected result
Glorious perfect hardware accelerated pixels
Actual result
On one of my machines, when OpenTTD is launched using OpenGL, quite frequently when the window first appears it is filled with uninitialised pixels. This is then later replaced with black followed by the title game screen/menu.
Depending on how loaded the machine is and whether it is a optimised/debug/etc build, this can be a coloured flash or last for a few seconds or so.
The GPU is a AMD Radeon R9 270.
-d driver=4
outputs:If a new user were to notice such an effect the first time they ran the game it could set a bad first impression.
Steps to reproduce
I assume that this is highly hardware and OS/driver dependant.
