I had the same problem with darkplaces a while ago discussed in this thread:

http://quakeone.com/forums/quake-hel...flicker-2.html

Never found a cure.

I just tried hammer of thyrion and am getting the same issue. Anyone else having this issue of the screen flickering everytime a level loads? If I tab out of Hexen and go back, the flicker stops, but it happens again once I enter a new map section.

It will also go away if I change and apply resolutions, but it happens again next time I enter a new area. I also noticed that the loading bars do not seem to move right before it starts to flicker.

Using the latest version and running the gl exe. The software one works fine.

The gl_ztrick doesn't help. The game and desktop are running at 32 bpp.

Here's my specs:

windows xp. service pack 3. gateway laptop with centrino duo.

Mobile intel(R) 945 express chipset family
Driver: igxprd32.dll
Vendor 8086 device 27a2 subsys 461107b revision
loaded d3dx version 42 (d3dx9_42.dll)

Running in fullscreen 800x600x32

Windowed mode doesn't seem to have the same problem, but I can't stand windowed mode. :(

    Thanks for the report and the details.

    I think the issue is related to the drawing of the progress bars during every level load which draws to GL_FRONT and is evil and possibly problematic with intel's drivers.

    We'll see what we can do.

    OK, here is a test build: Essentially it disables the drawing of the progress bars during level loads, therefore, if I identified the problem correctly, there must be no flickering issues under no conditions. Please test this and give us feedback.

    Just got to try it out and it seems that the flicker is gone. I quit, and reloaded/restarted, went back and forth through levels. It seems to be fine now. I noticed there is no longer the client/server loading bar anymore. I'm guessing that was part of the problem? Never liked that thing anyways. :p

    Yes, the problem was with the way the progress bars implemented in hexen2.

    I applied the patch to the svn repository as of rev. 4629, so the issue is now fixed. The fix will be integrated in the next release. The source changes can be followed from the svn: web/svn link for rev.4629:
    http://uhexen2.svn.sourceforge.net/viewvc/uhexen2?view=revision&revision=4629

    Closing as fixed.
