Some allegro 5 functions not working on some laptops

I noticed my "Startrek game" does not draw the stars when run on a lenovo thinkpad with Nvidea Quadro P520. The stars are drawn with al_put_pixel.. all other graphics and primitives seem to work fine...

Also the timer events are not triggered...
Tried it with a simple skeleton program, same results...

Any idea's why this could be ?

works fine on Desktop and other laptop computers (Acer)
???

Is this a known issue ? and is there a workaround

Windows 10

I tried using Visual studio with the NuGet version of Allegro 5.. same result
( I usually use MinGW)

Besides.. the NuGet package for allegro works very nice ;)

I don't set DirectX or OpenGL
everything is 2D

So that means you're using the DX driver. I'll ask again, are their drivers up to date?

Do they have integrated or dedicated video cards? Do they have both? Can they try both?

I did a quick test.. when using |OpenGL as mask addition to the display flags, the stars are visible again, so it seems to be a direct X problem indeed.

the drivers should be up to date, this thing is brand new..

however this is not a logical explaination for the Timer not being triggered .. or is it ?

nope still no Timer events..
I've put up some small test game thing.. it's calles simant, since I wanted to make it into an ant colony sim at some point..
I use it now to test my Astar scedule

the problem is in CustomProgram::onTimer ;)

should be triggered but it isn't
