Switching windows cause some issues in game

[GuardianDll]

Describe the bug

Sometimes, when i switch CDDA window to another one, and turn back, it causes several problems:

• Each switch reset the minimap window, like its in complete dark:

normally working map: map after switch map when i walked few tiles after switch

• Sometimes it also causes a black screen for the whole game window, without the way to fix it

• Once ive got the second bug on the map menu, and all map was visually corrupted

Map without a bug Map with a bug Map, if you move the camera to a few tiles

Steps to reproduce

1. Play game
2. Switch your game sometimes
3. Bug (I cant find any another reasons, it feels pretty random)

Expected behavior

not having a bug

Additional context

It can be related to some stuff with my system, i think, i played cdda while before but never has any of this issues

UPD: looks like second issue also can be fixed by making some stuff that reupdate the window, like open minimap if bug happened in main screen and vice versa

UPDD: Second issue provides when the error occur, and can be fixed by pressing I

Could you please post the contents of your config folder?

[GuardianDll]

yes, of course dont know which file you need, so ill send you all of it config.zip

[hexagonrecursion]

I am sorry, but I could not reproduce your issue even by using your config. What method do you use to switch to a different window? Alt+Tab?

I wonder if this is only reproducible on windows since it works fine for me as well, since I am also on Linux

[GuardianDll]

as i said, i believe it related to my PC itself - maybe some driver stuff or version of Windows if it was a more common bug it should have got way more bug reports about it than it has now

[NetSysFire]

I wonder if it might be related to hardware acceleration or something similar, did you try changing the renderer in the options?

[GuardianDll]

Ugh, i never thought about it just changed direct3d -> direct3d11, and looks like it was fixed sorry for spending your time, and thank you

[hexagonrecursion]

I wonder if it might be related to hardware acceleration or something similar, did you try changing the renderer in the options?

I tried "software", "opengl" and "opengles2". There was no direct3d or direct3d11 because they are Windows-specific.

IMHO this should be reopened - either we should drop the support for "direct3d" (BTW: what precisely does this option stand for and how does it differ from "direct3d11") or we should fix the bug.

[NetSysFire]

GPU stuff may be arcane. If it is reliably reproducible with direct3d this is definitely a bug. If not, it may be some weird driver shenanigans. This needs further testing.

[hexagonrecursion]

This needs further testing.

In this case this should be reopened.

I swear I had the same problem when playing my game on windows... But I can't reproduce it anymore, I will update here if it shows again while playing.

[philipdnichols]

FWIW I'm able to reproduce this on 0.G stable in Windows on the direct3d renderer and the problem went away when I switched to direct3d11

Using direct3d or direct3d11 or direct3d12 or opengl or opengles2 (all renderer options) The overworld map does not go black when alt-tabbing. The minimap goes black when in normal game screen or in overworld map screen

Before picture: After alt-tabbing out and back into CDDA: After moving a few tiles to the left:

/Confirm Not sure about all the different renderer options but I'm seeing this happen occasionally on default graphics settings.
