#680 game crashes in higher resolutions than 1600x1200

If I try to run the latest version of doomlegacy in higher resolution than 1600x1200 the game crashes all the time when i start level. Game menu works fine. It happens all the time with both software and opengl renderers and with both ultimate doom and doom2 wads.

The largest resolution that DoomLegacy supports is 1600x1200.
That is the largest that appears on the video mode menu.
The current code has to reserve memory for the longest video line possible, on every draw seg. Until I can make that independent of the max video mode, I do not want to support larger sizes. I find that large video sizes slow down the render, and 800x600 gives a fairly good appearance.

Render sizes that exceed 1600 in width will exceed the allocated draw seg memory. That is probably what causes your crash.
DoomLegacy has to be compiled with a larger MAXVIDWITH, for that to work.

Are you specifying a video size greater than 1600x1200, on the command line ?

I tried a few times with

dl -game doom2 -width 1800 -height 1400

It did not crash on startup, but I expect it would on trying to play a level. I got a large window that exceeded the size of my screen, that was a little blurry (OpenGL).

I changed the resolution by manually editing the config.cfg. It doesn't crash immediately after start. It crashes as soon as the level starts or as soon as the "demo" starts running on the background.
