Display Scaling is COMPLETLY BROKEN.

[cooldudeseven7Dev]

Hello, RoR community! I have an unfortunate issue while using RoR. When I set my display settings, to hd resolution (1920x1080), on arch linux, WITH fullscreen (in the app)- I come into this 1: No fullscreen, even if enabled- i see the dock 2: The scaling is broken- Even without fulscreen! Heres how it looks with fullscreen: Overlapping corners, and gui [Cant get the whole screen] Settings:

** My app is from itch. This happens on stable and devel.

Hello, this is unpleasant indeed, but looks like hardware/driver issue, nobody reported anything similar before. To help you, at the very least I need your RoR.log file, it should be in ~/.rigsofrods/logs. I'm a windows user/dev myself so I can't advise much but your OS build and Mesa drivers (or other if that's the case) would also help. @tritonas00 Arch expert needed :)

What GPU are you using?

[cooldudeseven7Dev]

What GPU are you using?

An Intel Graphics 620, Which works fine on windows and [some] linux distros.

Arch Expert Indeed! I used the itch version to use Rigs of Rods

Also, I need to reset the config, as i acidentally made the display unusable on my small display.

RoR.log has a line that says: 01:20:01: GLRenderSystem::_createRenderWindow "Rigs of Rods version 2024.03-dev-f6de162", 2560x1600 windowed miscParams: FSAA=0 border=fixed gamma=No vsync=Yes Is 2560x1600 the right size? Also, please include RoR.cfg, it may be useful.

No, Not at all! I need HD res, aka 1920x1080. Also, here is the RoR.cfg. [Its not supported, so here is text form]

I cant even fix scaling anymore, because I cant see with the weird res, probably that 2560x1600 you said. Like I said, I need 1920x1080 [HD Resolution]

The authoritative renderer config is in 'config/ogre.cfg'. Just stop game, edit it, start game and you're going. This is what mine looks like:

Render System=OpenGL Rendering Subsystem

[OpenGL Rendering Subsystem]
Colour Depth=
Display Frequency=N/A
FSAA=0
Full Screen=No
RTT Preferred Mode=FBO
VSync=Yes
VSync Interval=1
Video Mode=1440 x  900
sRGB Gamma Conversion=No

@cooldudeseven7Dev You said that you selected "1920x1080" in settings and ended up using something else - can you test it again? If that's true we have a bug in the Settings UI. The selector works by listing "supported resolution modes" from the renderer, which in turn gets it from the driver. Apparently your driver lists everything that the GPU can handle, ignoring the fact there's no actual monitor which can handle it.

Actually, I am connected to a mirrored monitor in HD, and it usually works. Anyways, let me edit it.

I have

And my GPU can handle It. View in overview:

It might be because of my activity bar? but it should work...

[CuriousMike56]

@cooldudeseven7Dev Yes, the Linux version doesn't take system UI into account: Only workaround is to enable full screen or set a lower resolution.

Interesting, But the same problem is also With Fullscreen! The side and slight bottom of the window still clips out.

As seen here:

[ohlidalp]

Interesting, But the same problem is also With Fullscreen!

are you sure you tried both options? I mean fullscreen with UI-scaling on and off.

[cooldudeseven7Dev]

Yeah. By the way, what is UI scaling?

also, your checks failed.

Will your update be on itch.io's RoR app? Experimental or stable, if so? I installed using itch, and I am on arch.

[Strikethru = outdated content] So, What do you want me to do exactly? Build your version?? Its on a different branch too...

Also, what do you mean by UI scaling?

[ohlidalp]

Oh, I've got a typo there, IDK why only the linux build failed.

By UI scaling I mean the option to make all buttons/labels/progressbars and other UI elements bigger, like Windows has: IDK if/how Arch does this but I thought it may play a role.

[Miner34dev]

I can confirm that option exists (at least in KDE). If helpful, i found it in display configuration.

I am in GNOME, So looking at my settings: here they are:

[cooldudeseven7Dev]

I'd just like to say, Is anybody on this thread anymore???

[Miner34dev]

What's your display resolution? If the two displays have a different resolution it might cause some issues.

[cooldudeseven7Dev]

What's your display resolution? If the two displays have a different resolution it might cause some issues.

Mirrored Display, 1920x1080 (HD Res)

[Miner34dev]

And the other display?

[cooldudeseven7Dev]

And the other display?

Both are not the same size. Monitor - 1920x1080 Main Screen - 2736x1824 But, My main screen is set to 1920x1080, and i mirrored displays.

I finally fixed the typo which was breaking Linux build.

Would you like me to clone your repo, and build it? I am not exactly sure how to do this, because its on a different branch.

thank you, cooldudeseven7Dev

Thank you by the way

[ohlidalp]

Hello again, apologies for the response lag, daily job kept me busy.

Thanks for testing with the extended logging, unfortunately it didn't provide any new insight. No errors, all reports consistently say 1920x1080.

Is it possible your monitor is distorting the image? I own an ultrawide 3440x1440 and when I launched with 1920x1080 fullscreen, I got a correctly sized image with black stripes on both sides (monitor "Aspect ratio" setting: "Auto resize"). The other settings I have are "21:9" (stretched to all available space) and "4:3" (slammed). If you have an option to try with a different monitor, it might be interesting to do that.

Other than that I have no advice, just improvised suggestions:

• I noticed you're running 120Hz ... try the classic 60Hz just out of curiosity.
• Try other fullscreen resolutions and tell me which have issues and which not.
• Also try various resolutions in windowed mode and tell me which have issues.
• Do you have any other OpenGL app to test with? Try also with glxgears pls - not sure it has fullscreen though.
• If all else fails, try building OGRE 11.6 and running it's demos to see if they exhibit the same problem.

Sorry for the late reply... I dont even use 120hz though.. I have a max 75hz display, and I am mirrored? I am connected to my laptop. glxgears works! I also have noticed something- I can run OpenBVE (a train sim, but im not sure if it uses open gl!)

I take it that the problem only happens on the external monitor, not on the laptop screen. Either way, tell me which resolutions you tried on either one, please. Also try without the mirroring, just the external monitor or laptop screen.

I also have noticed something- I can run OpenBVE (a train sim, but im not sure if it uses open gl!)

OpenBVE githup page says: OpenBVE is built in OpenGL, using the OpenTK framework for windowing. - I take it you don't experience any issues there?
