[🐛] Custom resolution resets to matching

[JakeSmarter]

Linux Flathub v1.10.000-28-ge19bcde1+

Whenever you return to the graphics settings menu, any custom resolution is reset to matching. However, the custom resolution is saved and loaded whenever you launch a “The Force Engine” instance, as long as you do not go into the graphics settings menu.

Furthermore, setting a custom resolution width basically does nothing for you, that is, it does not automatically change the height with the correct aspect ratio applied. However, setting the height does automatically change the width with the correct aspect ratio applied. But, the width UI field does not visibly change its value. 😵‍💫

[JakeSmarter]

Automatic custom resolution adjustment in both dimensions works as expected if “Widescreen” remains unchecked. If “Widescreen” is checked then automatic custom resolution adjustment only works when modifying “height” (without updating the “width” field).

Going back into the graphics menu always resets any custom resolution to “matching”.

The culprit is frontendui.cpp::pickCurrentResolution(), I'll try to fix it if lucius doesn't beat me to it.

You want to give this a try? It works(TM) for me:

🥳 Finally, I was able to test your branch but I did not review the code (this is something for @luciusDXL to do). The custom resolution does not reset to “Match window” any longer when you enter the graphics menu. However, automatic custom resolution adjustment is gone completely now. 🙁 So, this is something that may need to improve.

The custom resolution does need more work, I agree. It isn't used very often and hasn't been well tested.

It is a very good idea and very useful though. 👍 Ever since I discovered this feature’s potential and capabilities I use it permanently, hence me complaining that it resets although it is saved. It is especially useful for configuring exact multiples of native screen resolutions because this is something that is not always possible with EDID reported resolutions by monitors.

Properly used, it can produce a nice retro effect on high resolution monitors and at the same time improve fps rate. 😉

Can you please elaborate? I'll try to fix this too.

Given an aspect ratio, if you enter the number of pixels for any dimension the UI automatically computes the correct number of pixels for the other dimension and updates the field.

In v1.10.000 it works best if “Widescreen” is clear. Try to enter any numbers for either width or height and observe how the other field (for the other dimension) is updated automatically.

@luciusDXL Btw, as much as I appreciate the “Widescreen” checkbox (and effect) imho “Widescreen” as a term is a bit inconclusive: when is a screen wide enough to be considered as wide? Hence, it would be nice to have more control over the exact aspect ratio via a drop down menu or combo box with an enumeration of common aspect ratios, like 1:1, 5:4, 4:3 (default), 16:10, 16:9, 21:9, etc. Maybe even the option to specify the aspect ratio freely.
