Mouse Cursor exiting screen

[LegoStax]

I am having a problem with the mouse cursor partially "exiting" the screen. What I mean is that the cursor image stays within the bounds of the screen, but it seems as though the internal cursor position exits the normal bounds of the screen. For example, if I move the mouse against the left side of the screen and continue to move it, the cursor image will stay where it should. After moving the mouse continuously to the left, I move it back to the right and the cursor image appears to stay against the left side of the screen until the internal mouse position has moved back into the bounds of the screen. This also happens with the default system cursor.
I am using the "desktop" mode for fullscreen. I have also tried "exclusive" mode to no avail.

For those that read the code: I realize that my drawing of the cursor is inefficient as LOVE supports the ability to set the system cursor. However, I found that setting the system cursor causes it to glitch and become a white box if it is moved to the bottom right corner of the screen.

I have built LOVE from source on the Raspberry Pi 3. Hence, I'm wondering if this is an issue with Raspbian Jessie Lite, SDL, or LOVE (and how to fix it of course ).

If it helps, I get this error on Raspbian, but it does not stop the code from running:

Code: Select all

AL lib: (WW) alc_initconfig: Failed to initialize backend "pulse"

Research tells me that it's an issue with sound, which I do not need.

It's also attached.

LÖVE does not support detecting the mouse cursor position outside of the LÖVE window (it's not a bug).

But if you haven't already, you can do [wiki]love.mouse.setGrabbed[/wiki] and that will restrict the cursor to always be inside LÖVE's window.

Eh, don't worry. Audio probably works, at least it does in my game, even though it errors exactly like that.

Thankfully, as indicated by the W, it's a warning, not an error. OpenAL soft tries a number of different backends, one of which is PulseAudio, but another common one to show up in those warnings is JACK. If you have installed the relevant client libraries (libpulse or libjack, respectively), OpenAL soft will try to open them in some pre-determined order, which seems to be (at least) JACK → PulseAudio → ALSA → OSS. In your case, you have libpulse available, but pulseaudio isn't running, thus it can't create a pulse backend, then (probably) continues with ALSA. If you want to suppress the warning, you can disable backends in alsoftrc.

That's what I don't understand. I have done love.mouse.setGrabbed(true). I tested it to make sure that it works by trying it without fullscreen. Here's a video of my issue.

Wow, now that's a nice bug report.
If you think it may be your compiled version or something of the sorts (which i somehow doubt), you can try this:

I actually already have tried that distro. I couldn't get PipaOS (which is what it's based off of) to work with the Raspberry Pi 3's wifi card, despite following the instructions on the pilove.mitako.eu website. Moreover, it still produces the same glitch with the mouse cursor.
I'm currently working on setting up LOVE on Raspbian Jessie (not Lite) to see if having xserver and openbox already installed and configured will help the situation (Raspbian Jessie Lite doesn't have those). I'll post the results here.

I report that LOVE does not work on Raspbian Jessie (not Lite) at all. There's an error with SDL when running it in the desktop environment. When running LOVE from the command line, outside of the desktop environment, then the screen is covered with Raspbian's colormap that displays on boot. Hence, the only way to get LOVE to work at all is on Raspbian Jessie Lite.
Unless someone finds a way to fix the cursor issue, it looks like we're back to square 1.
I'll file a bug report.
EDIT: A bug report has been filed.
