[Cuis-dev] Space is low

I’m not exactly sure how I got it into that state, but this may be related… I had saved the image while it was full screen on my 5K external monitor. I also had left the image running and the next time I woke the machine up and plugged in the monitors I found the image had hung. As Juan mentioned, if I opened the image, moved it to the 5K, and immediately set it to full screen then it would hang. I didn’t get the same space is low message, but what we tracked down was an allocation for the new screen that was failing.

Hi Folks,

Yesterday Jon Raiford saved an image that did something similar to what you Mark describe when starting it, moving it to a 5k display, and setting it full screen. We spent several hours debugging together. The result is updates #6569 and #6570, pushed today to GitHub. These updates do fix the issue as experienced by Jon. I'm pretty confident they'd fix what you Mark saw too.

Thank you Jon for finding a case we could reproduce, and for debugging it together!

Cheers,

The "Space is low" issue hasn't repeated itself for me in the past couple of days, but I'll report back if it does happen again. I did pull down the latest updates to Cuis a couple of days ago, so I suppose it's possible there was a recent change that fixed this.

What happens when you minimise cuis before letting it go to sleep?

I'm asking because this is what happens on my Mac - M2 Mini running Sonoma with LG 4K screen.

I usually run Cuis as a window - so not full screen. When the system goes to sleep, or the display sleeps, it quite often, although not always, will resize the window to a smaller size. Cuis isn't the only application that this happens to; citrix client will also have the same issue, again not every time, even though that is run as full screen. I've always figured this is some mac sleep quirk that I have to live with.

I haven't had the issue occur when I minimise the cuis window - although I have had the icon on the dock look like it's been resized - so instead of a 128x128 icon it's shrunk to say a 80x60 icon (guess).

Next time few times it happens I'll grab the size because now I think about it I'm fairly sure the resize looks to be about the same size every time.

I've not reported this before because I've never been able to consistently reproduce it.

Barry

A sleep of the Mac was involved.
I didn't move the window myself after it woke up, but I do have it on a second monitor, so when it wakes up I suppose macOS "moves it".
My Mac has slept several times today and did not result in a low memory exception on waking.
I inserted the logging code that Juan requested.
Perhap it will happen again tomorrow morning. I'll report back if it does.

Just thinking out loud here.

Based on what Juan mentioned, did you move the Cuis window between monitors (assuming that triggers a resize)?

Did the machine (partially) go to sleep in those 2 hours?  Does the
problem manifest when the machine transitions between sleep and awake?
