Panic on tilling window manager

[FloVanGH]

Some users of OrbTk reported a crash of the examples on tilling window mangers: https://gitlab.redox-os.org/redox-os/orbtk/issues/195#note_18953

Thanks for the report. I will take a look next week

[emoon]

I tried this on Linux and i3 window manager (noise example) and I'm not able to reproduce the crash panic. Is there some more info on this what is required for this to fail?

The crash occurred on a normal gnome desktop as well. Looked like it was the resize event that caused it. My tiling wm (sway) created a small window then resized it to be larger than some buffer.

And does this happen on a specific example in minifb as well? (like the noise one)

Of note, the noise and mouse examples work fine. The menu and title_cursor examples do not give the same panic but I also suspect they do not render correctly:
menu:

title_cursor:

Cool. Thanks for the report. I'm going to work on this today

[emoon]

So update on this and how I will fix it is in #113

[FloVanGH]

Thank you, it works now if I ignore the the result error of update_with_buffer_size. It's the same error message as before. And during the resize you could see sometimes the same visual effect, almost by downsize.

[emoon]

Cool. Yeah I'm currently working on fixing all of the resizing issues. I will add some extra options to WindowOpts that allow you to set how the resizing should work (as it's different depending on your application)

[emoon]

@stevensonmt hey, if you have the possibility of grabbing the latest minifb, switch over to dev branch and try this again that would be awesome. I hope it should all be fixed now.

[stevensonmt]

@emoon,
Can confirm fixed on dev branch. Thanks for your work on this!

[emoon]

Awesome! Thanks for checking :)

[FloVanGH]

@emoon I can confirm that to. Thank you :-)

[emoon]

Thanks! Moving over to doing mac fixes now

[emoon]

Closing this now as 0.15 has been released with the fixes for this
