Hi,
I am using Flame 2026 trial on macOS.
Some times I leave apps open and only close the screen to have some break.
What I noticed with Flame 2026 is that after reopening my screen, Flame UI has gone bigger as it was zoomed in and it says Flame (not responding). I can only force quit.
Any Idea what is causing this behavior?
That is expected behaviour. When you close the lid screen res resets. You should exit Flame before closing the lid and changing the screen res.
OK, that will be hard thing to remember 
You could instead lock the screen for your break rather than close the lid, OR you could electrify the lid so you don’t try to close it. But I feel like the first option is probably better.
