Automap aliasing (?) issue

[observeroftime01]

Necessary details:

Command line parameter using dsda-doom-0.27.5

"./dsda-doom.exe" -iwad "DOOM2.WAD" -file "10X10.wad"

Onto the issue: My automap looks like this, which makes it borderline unusable. No, this is not a screenshot artifact, it looks like this no matter the zoom level.

Enhance:

Even rotating the map (yuck) does this, but it becomes somewhat more usable:

I think making the lines a pixel or two wider would solve this issue on my end, but I can't find the relevant configuration parameters (if such a thing exists). The artifacting / aliasing issue exists no matter the resolution (3000x2000 is my native resolution though). I thought I'd check a tangentially related source port PrBoomPlus to see if the issue exists there also, and it does not. Really no other video-related or other issues present, the application runs absolutely fine otherwise and I am shocked at the performance of my ancient Surface Book. The issue is also not present on my desktop system, so I'm afraid it might be something about my laptop.

I have tried:

1. Different video modes
2. Different resolutions
3. Fullscreen or windowed
4. Deleting my dsda-doom.cfg
5. Trying out a fresh install
6. Playing a different pwad entirely

If this is a case of PEBKAC feel free to close the issue and I apologize for wasting everyone's time, although I hope the person who read this learned a useful acronym at least. If this is a legitimate issue, I would appreciate any advice to remedy the situation. I have already written half a novel where a picture would have probably sufficed, so if any more details are needed I'd be happy to provide them.

Thank you for your time.

I can reproduce on fullscreen resolutions larger than native

SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "1") makes it better, but still awful.

I can reproduce on fullscreen resolutions larger than native

SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "1") makes it better, but still awful.

Is this an option I can set in the config somewhere or is this code that needs compiling? If it's a config option I will try it (though I can't find "SDL_HINT_RENDER_SCALE_QUALITY" anywhere), otherwise I'm in over my head. The bottom image at least looks better compared to the other image with the gaps between the lines. That makes looking for switches, secrets and such quite a challenge.

I have also just double checked that the issue is present in all resolution presets on my end, native resolution or otherwise. Here's a screenshot from a 1920x1080 at a 16:9 ratio:

Screenshots

Interestingly, I tried OpenGL video mode one more time, and the issue is not present there for whatever reason. When I first submitted the issue I swear I tried OpenGL video mode, but hey, maybe this helps track down the bug. It appears to be related to the software render (I know, super helpful...).

Thank you for successfully reproducing the issue though, makes me feel a little less lonely with my issue 😅.

[andrey-budko]

I don't think I reproduced the issue in its original sense. It's normal if after scaling down using nearest neighbor filtering, lines with a thickness of one pixel can disappear. Not sure why this happens with native resolution and even windowed. I think that in this case scaling should not be applied.
