Pokedex example crashes when the window is resized to 0 height

[pantsman0]

I just checked out the repo to give it a look, and I was trying some of the examples.

I ran the Pokedex example on Windows 10 Pro (10.0.18362 N/A Build 18362) and it was running great... until I resized the windows so it had 0 height.

It crashes on the error thread 'main' panicked at 'calledResult::unwrap()on anErrvalue: OutOfMemory(Host)', C:\Users\pants\.cargo\registry\src\github.com-1ecc6299db9ec823\wgpu-native-0.4.3\src\device.rs:2091:9.

seeing this when minimizing an iced window on hybrid GPU systems like laptops. Doesn't happen on discrete GPU system like my tower.

I was able to reproduce this today. Some PCs I tested on crashed, some did not. The ones that did crash both use hybrid graphics.

[kurnevsky]

I can reproduce it on both discrete and integrated GPU. I use linux with mesa.

Hmm... almost a year passed, how could i avoid this crash?
