Bug description

When the screen refresh rate is set to 165Hz, Luxtorpeda is unable to display engine choice and crashes. If the screen refresh rate is set to 60Hz, it works as expected.

I've encountered this only when trying out Caesar III. I have Arx Fatalis running just fine at 165Hz or 60Hz. This could be an issue with games that have multiple engine choice, like Caesar with Julius and Augustus engines.

Steps To Reproduce

Set screen refresh rate to 165Hz;
Start Caesar 3;
Crashes with error thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: SdlError("Window is too large.")', src/ui.rs:514:10.

Expected Behavior

Should display a choice selection between Julius and Augustus game engines and launch the game.

Answer 1 · 2022-08-26T14:17:38.000Z

@sekanS Thanks for the report. Could you provide a log of the working case with your 60hz refresh rate?

It looks like the dpi scaling is trying to create a resolution for the window that's too large, hence the panic, although not sure why the refresh rate would affect that.

Answer 2 · 2022-08-26T14:50:22.000Z

Here is a full log of starting the game using 60Hz.

Answer 3 · 2022-08-26T18:11:02.000Z

@sekanS Are you on x11 or wayland? If on x11, can you run the following command on both cases and send the result here?

xrandr

Answer 4 · 2022-08-26T23:24:28.000Z

@d10sfan I'm almost always using X11 (especially when gaming). All tests so far were made on X11.

Either way, here is the output on X11:

$ xrandr
Screen 0: minimum 8 x 8, current 2560 x 1600, maximum 32767 x 32767
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
DP-3 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)

   2560x1600     60.01 + 165.02*

And here is the output on Wayland:

$ xrandr
Screen 0: minimum 16 x 16, current 2560 x 1600, maximum 32767 x 32767

later edit:

I've made another test. Used Wayland and left the refresh rate at 165Hz. The game ran just fine. So this issue seems to happen only on X11 @ 165Hz.

The log below is of successfully starting Caesar III on Wayland @ 165Hz:

Answer 5 · 2022-08-27T16:16:44.000Z

@sekanS It looks like in your wayland example the dpi variables are correct, instead of very high like in x11.

Related to this: found dpi: (4064.0, 96.0, 96.0) using dpi: 4064.0

Recently, SDL2 added a warning about using that API, which seems to have been added because of issues with accuracy on sdl2: libsdl-org/SDL@307b0b7

So it may mean I need to switch to another way of determing the scaling needed. For now, so it does not crash, I could look at detecting a high refresh rate and x11, and disabling the dpi scaling attempt (or at least ignoring the high value). Are there other refresh rates that your monitor supports that cause this issue as well?

Answer 6 · 2022-08-28T00:50:50.000Z

@d10sfan I'm using the laptop's screen, and I can only go either 60 or 165 Hz, nothing in between. So, unfortunately, I can't test different higher refresh rates to see if others would cause problems. My external monitor is only going as high as 60Hz, no luck there either.

It's a good think you found that API warning. Gives it a bit more perspective now.

Answer 7 · 2022-08-29T04:31:28.000Z

@sekanS I created a workaround for this in #169

There's a build at https://github.com/luxtorpeda-dev/luxtorpeda/actions/runs/2945899483 if you could try it and let me know if that fixes the crash and still look ok.

I'd still like to look at how the dpi scaling works in the future to see if the calculation can be fixed, possibly by using other sdl2 features than getting the reported DPI.

Answer 8 · 2022-08-29T10:16:03.000Z

@d10sfan I tested the new build, and it's able to run at 165Hz, but the window is blank now:

Switching to 60Hz displays the window properly, as expected.

Here is the output of the run at 165Hz:

Answer 9 · 2022-08-31T00:04:44.000Z

@sekanS It looks like there was another spot where the dpi needed to be fixed. Can you try the build from this? https://github.com/luxtorpeda-dev/luxtorpeda/actions/runs/2960412707

Answer 10 · 2022-08-31T08:54:24.000Z

@d10sfan Tested the latest build and it works perfectly fine.

Answer 11 · 2022-08-31T20:32:17.000Z

@sekanS Thanks for testing! I've released a new version with this fix. Let me know if you run into any issues.

Answer 12 · 2022-08-31T23:31:27.000Z

Works like a charm. Thank you, @d10sfan! 🥇
