Any idea why this is happening? When I put DOSBox into fullscreen mode on my laptop, the video outputs a burned in light pattern onto my LCD and then locks it up. I have no idea how else to describe it.
I can't figure this out. I can go fullscreen with all other applications, emulators, video players, games, video hardware test/benchmarkers, etc.
This is really freaking me out and I wonder if I am damaging my laptop by doing this. Whenever I select fullscreen via ALT-ENTER, it just burns out the screen. It's not just case of the backlight flooding the screen because the process is slow and you can see the pixels developing different gradients and there are rough patches that streak up and down the display with a very grainy pattern.
After this occurs, I cannot revert the screen to normal and I'm forced to power-down the system. I cannot restore the window via ALT-ENTER or ALT-TAB, or shut down DOSBOX with F9 or ALT-F4 (at least not to my knowledge because I can't see anything on the screen). CTRL-ALT-DEL may be bringing up the task manager but I can't see if it's working but it won't shut down this way, I have to hit the power.
Here is a video, it's really eerie, the pixels develop this scorched, overexposure pattern that varies each time I do it. I really am afraid I am damaging my LCD panel but I really want to get DOSBox to function in fullscreen.

What you see in the video isn't glare or anything, it's the actual display along with the strange white streaks and rough patterns. Looks like a bad photocopy, radio noise, or maybe the Shroud of Turin or something 😵.
The only times I have been able to get DOSBox into fullscreen was by starting DOSBox, then changing my display color-depth while DOSBox is running, then if I'm lucky, it will goto the correct fullscreen mode and be fully-functional and restorable. What routine does DOSBox use to switch between windowed and fullscreen display? I think very much a DOSBox centric problem as I have no problems with any other apps so it's not a generalized hardware problem. DOSBox functions perfectly on my Desktop 17" LCD.
On reboot, everything returns to normal but I'm sick of doing this everytime I attempt a DOSBox fullscreen. DOSbox is fully functional in windowed mode.

Any ideas? Wild guesses? Conspiracy theories???
