Screenshot corruption in OpenGL mode

[charcola]

Basically the above. Playing on an hp 3105m netbook with opengl enabled at 1366x768, taking a screenshot results in this:



Screenshots look fine in software mode. I haven't done much testing or fiddled with settings, and the game itself runs fine, it just seems to have this problem taking screenshots with Zandronum for whatever reason. skulltag seems to take screenshots just fine in openGL.

I believe screenshots don't work at that resolution. I'm curious how it works on Skulltag though, since this problem was long before Zandronum. Are you running Skulltag at 1366x768, too?

I have the same problem, and i'm running Zandronum at 1366x768, however, programs like FRAPS don't have this problem when taking screenshots in Zandronum.

Yes, Skulltag had the same problem, but GZDoom doesn't, even running at the same resolution.

It was fixed some time ago, had something to do with resolutions not being mod4 and thus bugging out due to a performance optimization. (Or shall we say non-degradation.)

What I would do is either:
Try to load your INI from Skulltag to see if it has the same problems
AND
Try a fresh ini and change settings on-and-off until you can find the specific setting that causes this problem, so we can attempt to reproduce it on our end (with an appropriate bug report when the problem is located.)

[Bloax]

No, the problem is the resolution itself. 1366/4 = 341>.5<

And if my fuzzy memory serves, it lies in the way the screenshots are taken.

use 1360x768

[charcola]

Looks like changing to 1360x768 solved it. Strange though, I could have sworn that I didn't see that mode available as an option the last time I tried checking the resolution options.

I think Skulltag must have been using a different setting as well, it was using 1280 x 768, yeah.

This is clearly the work of Slenderman. Don't turn around, charcola.

It's a GZDoom bug that has been fixed in GZDoom but is still in Zandronum, see the tracker ticked: http://zandronum.com/tracker/view.php?id=920
