Openbci_gui: GUI Drawing Error on Lower Resolution Screens

[espinoj]

Problem

Cursor is pointing above the area of where it is rendered

Expected

Rendered cursor and active area are in alignment

Operating System and Version

macOS

GUI Version

5.0.1

Running standalone app

Both processing and downloaded build

Type of OpenBCI Board

None. Loading files.

Are you using a WiFi Shield?

No

Console Log

No errors in log

[retiutut]

Please provide screenshots or link to a video recording. Renders fine on many Mac, Windows, and Linux systems.

Also, without a Console Log there is no record of what buttons were pressed or how the GUI was configured.

[espinoj]

I figured out the conditions under which this occurs. On low resolution screens, the upper dark blue menu bar is not rendered (maybe under the window bar) and the cursor is off calibration in the vertical direction. The workaround is to increase screen resolution.

[retiutut]

Still no console log to confirm details....

On low resolution screens,

But the GUI has not been resized and in this example has loaded with the default size.

//set window size
int win_x = 1024;  //window width
int win_y = 768; //window height

    // If 1366x768, set GUI to 976x549 to fix #378 regarding some laptop resolutions
    // Later changed to 976x742 so users can access full control panel
    if (displayWidth == 1366 && displayHeight == 768) {
        win_x = 976;
        win_y = 742;
    }
    size(win_x, win_y, P2D);

I have my screen resolution set to 1280x800 and yes I have not resized the screen when the dark blue area is inaccessible.

Operating System and Version

macOS

But you leave out Mac OS X version? This is why there is an issue form. Excluding all of this information is making it very difficult to help.

? Gui says otherwise.

Sorry that was console after I changed resolution as a workaround. Was tricky figuring out where the console button was but here is the paste:

Try letting this Mac run on the default screen resolution.

Also, you really should update your Mac OS. Your computer is 4 years newer than mine, but 2 major versions behind.

Replicated on MacBook Air by changing screen resolution to 1280x800

@espinoj Thank you for providing all necessary details to help determine the root cause of this issue. It looks like when I remove the minimum GUI size constraints, it works just fine. So, this can be fixed soon and I have upgraded this to high-priority bug fix. Development branch is currently on v5.0.2-alpha.4, and I would like to resolve this issue and merge a fix in the next week or so.

I believe I have the same issue on Windows 10. The mouse pointer has to be significantly below whatever option it's trying to select.

Could have more to do with screen resolution than the OS. Looks like you guys may have figured that out, but just wanted to make sure you know it's not OS-specific.

[retiutut]

The GUI will no longer impose minimum dimensions of the app, but will still wait every ~500ms to resize the drawing area to hopefully avoid crashes.

This seems to be the best fix for everyone, and it somewhat mirrors the behavior of VS Code. This should allow users on lower resolution screens to run the GUI without drawing errors. Tested on an older MacBook Air with lowered resolution to 1024x640.

Here is a screenshot:

Might move the Issues button under the Help....
