Been trying out GLQuake on my Voodoo 3 3500 TV, and of course, it runs really smoothly. However, I get some elements of the HUD flickering, such as when a number chances, it flickers between the new number and the old number continually. It can also flicker between the HUD and fullscreen effects like the console "door" which closes over the whole screen between levels; the 3D area displays just fine but the part over the HUD can be glitchy and flicker.

I have searched online but the results always seem to be for the Steam version (and not what I'm talking about anyway) or some other Quake entry. This is just about retail Quake, running on Windows 98SE, patched with GLQuake and nothing else.

If my description isn't clear enough then I can try and make a GIF of it, but basically the flickering is continual and alternates with every single frame (so like, alternating between an old element and a new element, at 60FPS).

Does anyone know any help for this?
