Screen flashes are broken on some maps

I reported the issue to QS, but it also applies to QSS as well.

I have the same issue, looks like its fixed in QS here: sezero/quakespasm@f09b26b

Hopefully spike can add this fix to the QSS dev build soon.

Is this referring to the screen flashing a solid color instead of a translucent one, thus leaving the player blinded? I'm having the same issue.

This is exactly what I'm experiencing as well. On ad_tears jumping in the water triggers it and totally fills up the screen with yellow until you get out of the water.
