[v3.6.0] Super-ultra-wide 32:9 framebuffer bug in Geoscape


Recommended Posts

I play this game on a 32:9 5120x1440p resolution, which is generally awesome as hell since you can see twice as much horizontally (entire levels sometimes). The Geoscape and menus don't support 32:9, rather 21:9. The problem is that the unused portion of a screen is not being cleared each frame. When I for example open Steam Overlay and have any window or "external content" rendered to the unused portion of the game, and then exit the overlay, it will be permanently printed to that unused space.

Not game breaking at all, loading any Ground Combat mission will eventually reset the entire framebuffer, but the issue will come back when you get back to Geoscape and open the overlay again.

EDIT: It only affects base screens, not the Geoscape itself. Geoscape will clear the framebuffer, not only Ground Combat.

Thanks for the bug report! Can you post a screenshot of the visual artifact that gets left over when you exit Steam Overlay? I might be misunderstanding what windows you're referring to but I'm also on a 5120x1440p monitor and I can't seem to repro the bug, thanks!

I'll do it later, but generally it looks as if Steam Overlay properly clears it's "canvas" each frame, but when you exit the overlay the windows dissapear smoothly, but the last frame somehow gets burned in the game canvas.

How to repro: go to armory/scientists/engieering screen, open Steam Overlay, put any window on the sides of the screen (above 21:9 ratio), exit Overlay and you should see a glimpse of the faded window from Steam Overlay printed in that 21:9-inaccesible area.

BTW. Which monitor do you have? I have Samsung Odyssey G9 Neo from around 6 months and been loving that piece of equipment :D I've ordered Ergotron HX Heavy Duty arm for it recently and on Monday I should get a delivery of a 2000x800mm standing desk, so I can't wait to properly finish my setup now :)

This is how it looks after I close Steam Overlay and some windows were outside 21:9 aspect ratio:

Another G9 enjoyer! :D I'm using the older miniLED G9 as I happened to find one on sale when I was building my current setup and I've been loving it so far! For the desk I bought the Bekant corner desk from IKEA and it seems to be working well enough. Let me know if the Ergotron arm works well because I'm also hoping to get a monitor arm for my PC but I've been skeptical of buying one due to the sheer weight of the G9 :P

For the bug, yeah - we're working on getting a fix around it which should drop within the next few patches :)

I've seen this issue being fixed in patch notes, thanks!

The arm is fine with the G9, but you need to buy the Heavy Duty one that is built specifically for G9 due to it's curvature and thus different center of mass. It looks a bit unreal that it can hold that weight and nothing happens to the monitor, but moving it is a bit harder than I thought. Maybe I could play around with some screws to adjust it but I don't really care, since I bought the arm to free desk space, rather than to have maneuverability.

Still some cable management left to do, but I finally have a proper gaming / work station :D
