All Build Engine games seems to get flickering on sprites if I use 1024x768 as my screen resolution (reads blood, duke3d, redneck rampage, etc). Is there any workaround to fix that?

I have a flickering issue with all Build Engine games when I play with 1024x768 resolutions, that doesn't happen in 800x600 resolution. All sprites flickers in duke3d 1.5, for example. @above poster: Check the air tubes in the bathroom. EDIT: Sorry, shouldn't have posted this here as it's a DOSBOX …
