[raiguard/posila][1.1.104] HDR causes broken rendering with KDE6

[Baughn]

Well, it's marked as an experimental feature and the checkbutton literally landed yesterday, but I thought I'd mention anyway.

If you enable HDR in KDE6, as such:


Then the rendering of Factorio breaks fairly badly:

It isn't visible in the picture, but the lakeshore tiles are actually flickering. The fix here is, obviously, to disable HDR; I'd estimate at least another year before this is useful. Though it would be nice if Factorio didn't do... whatever it's doing here. Blindly picking the highest color depth available, maybe?

Other SDR applications appear fine, and the black is too black, if that makes sense.

Post the log please, see 3638

This should be the one: https://brage.info/factorio-hdr-weirdness.log

I don't see anything unusual. The pixel format is still RGB888, so I would be suspicious of the compositor more than anything else. Though I don't think that could cause the weird shoreline rendering.

Interesting. We don't pick colordepth blindly for anything as far as I am aware. It is interesting that the problem is isolated to non-animated tiles and everything else seems to render correctly. Tile sprites use different texture compression format than other things do when Texture compression quality is set to "High". Could you try to set it to Low and see what happens. My prediction is that rest of the game sprites breaks too. My guess is that GPU accelerated texture compression breaks for some reason, but test at startup passes, so it's maybe GPU accelerated mipmap creation? Does it look like that even when you zoom in?

Code: Select all

   1.518 Texture processor created (2048). GPU accelerated compression Supported: yes, Enabled: yes/yes. Test passed. YCoCgDXT PSNR: 35.83, BC3 PSNR: 33.82

Also, Ctrl + F3 will open Sprite Atlas Viewer. Atlases 6 and 7 should contain tile graphics. Do they render correctly there?

This is likely an NVIDIA-specific issue, as NVIDIA on Wayland is still a bit hit-or-miss. I tested on my AMD 6800xt and it works just fine.

Please ensure that your NVIDIA driver is up to date.
