No. This bug is fixed.

Does this still happen?

On the hw_postprocess branch the palette tonemap is black because the second texture is somehow not bound correctly. I've spent quite some time trying to figure out why with little success.

I'll try convert the ssao pass to see if it magically repairs it, but given the problem I have with the tonemap I fear even if it fixes the original problem it might still remain broken.

Unfortunately [url=https://github.com/coelckers/gzdoom/tree/hw_postprocess]hw_postprocess[/url] branch has the same problem.
In addition, palette tonemap mode causes a black screen too.

It's on macOS, I cannot check on Windows at the moment.

That sucks. On the other hand, setting gl_ssao to 0 solved the black screen issue on my end as well.

I cannot check on Linux with OpenGL Core Profile but on macOS I managed to get black screen with Ambient Occlusion enabled, i.e. when [b]gl_ssao[/b] CVAR is not zero.
However in my case this affects menu and automap as well. It's just solid black screen regardless of game mode until AO is turned off.

Please note that refactoring of postprocess effects is happening in the different branch.
Most likely this will be sorted out before (or right after) merging into master.

Once I start a new game, load a saved game, start watching a demo or the titlemap, etc., the screen turns black, and I am unable to see anything. If I look at the automap, I see only a single white pixel in the center of the screen.

The main menu and console work just fine, however, except if the current mod has a titlemap.

Here is a startup log, if it provides any interesting details:
