4.0.4 bugs

[PowerWyrm]

Would it be specific to the sdl client or does it happen with the regular one? I've never experienced this in any of my games (although I'm using Windows)...

You mean flicker, tile disappearance or detect monsters subwindow issue? At least X11 client does flickering when always centering is on. Other issues I haven't tested. On the other hand, can you even play X11 client with tiles?

No, there are no tiles for X11. I just tested then, and was getting flicker with the SDL port (ascii or tiles), but not X11, so it seems a bit sporadic - maybe related to system load?

I'm testing on core i3 laptop and cpu load is ~1 %. In my system both X11 and SDL flicker constantly.

I suspect it's a fundamental bug in SDL port. I took a very brief look. It appears that there is no double buffering. Once upon a time I cleaned up the osx Carbon port. Double buffering was absolutely necessary. The same clearly was true for the osx cocoa port. Single buffering would be OK if moving the map simply moved a visible region around around on a very large GFX panel. However, since every map move requires a screen wipe followed by full redraw, double buffering is _required_. There is no other way to fix it.

Now that I'm playing... This is a minor cosmetic thing and probably has been reported already, but anyway, I'm browsing my spellbook with descriptions on and move from one spell to another. If the previous spell's description uses two more lines than the current one, part of the previous description is left on screen. And still running the SDL port on Linux.

That sounds like something I fixed for PWMAngband. Are you using big tiles (tile height > 1)? If so, I think the following code should help:

static void spell_menu_erase(void)
{
    int x, y;

    Term_locate(&x, &y);

    /* Hack -- always finish at the end of a tile in bigtile mode */
    if (tile_height > 1)
    {
        int ymax = ((y - ROW_MAP) / tile_height) * tile_height + ROW_MAP + tile_height - 1;

        while (++y <= ymax) Term_erase(x - 1, y, 255);
    }

    /* Hack -- if we use a distorted display, don't refresh the last rows */
    if (Term->max_hgt != Term->hgt)
    {
        if (--y > last_row)
            last_row = y;
        else if (y < last_row)
        {
            while (++y <= last_row) Term_erase(x - 1, y, 255);
        }
    }
}

Just call this (the distorted display part is probably not necessary -- PWMAngband has pseudo 3D tiles which require this) in the spell menu browser and it should fix the problem.

Not a bug. See below.

Visible Item List shows multiple rings on a square.

With the attached save file, when i quaff the potion of *Enlightment*, there are "3 Engagement Rings of Speed 7S 3W" listed in the visible item list.

When i move into line of sight of that place (easy with the mass banishment scroll), i see only one on that square, and then only 1 is listed. When i leave line of sight, the list again contains 3 rings at this place.

(note: i'm playing 4.0.3, but didn't read of this bug, so i assume it's not fixed yet)

I'd be interested to know what happens after @ picks it up. Are two such rings then listed in the object window? Multiple items of the same exact type, just as multiple monsters of the same exact type, are listed as to number, but the lat-long given is only that of the closest. In the object window, line of sight items are separated from objects "aware of". So, when moving into line of sight, I'd expect to see only one of the rings, but below in the "aware of list" I'd expect the other 2 to be listed. When moving back out of line of sight, you would then have 3 in the object aware of list.

Thanks. That's it. I never noticed it before.
There were 3 Rings of Speed (+10) on the level (and 1x +9, and 2x +8). It listed 3 rings close to me, and when i was in line of sight, i saw only that one, and there was a new entry in the "elsewhere" list for the other two.

A documentation glitch:

The in-game documentation (i.e. hit '?' and select "command descriptions") still refers to using 'B' to "bash" a door, or, alternately 'f' to 'force' a door (presumably, whose lock you are unable to pick). However, it appears that the 'B' command no longer exists (and hasn't for several versions), and 'f' means something else. I can 'tunnel' into a door, and this seems to work, but it's not clear if it is the same as "bash", or something else.

The command descriptions should be updated to remove "bash", and to make it more clear what "tunnel"ing into a door actually does.

So I just got a new artifact weapon and it seems pretty great, except there's so many abilities etc that it has that none of the combat information actually appears on the screen, so I have no idea how many blows, how much damage, etc., the darn thing does. Resizing the screen does not help at all. Moreover, after I inspect such a weapon, when I return to the main screen, the whole left hand side with character stats, etc., remains covered up by partial writing from the inspection, and is very difficult to get rid of.

Make a character dump and look at it that way? Post the artifact in the memorable randarts thread too.

I'm bug-reporting here.

So where is this needed?
