Qt5.5 application crased in unbuntu14.04 when resolution change

[waitianlou]

I development a simply application based on Qt5.5 in ubuntu14.04, it runs runs normally. but when i changed the resolution of ubuntu, it will crashed in most time, even Qt Creator will crashed too.

So I use the example of calendar, however it crashed too. How can i solve this problem or how can i see the log to find why it crashed.

Thanks for reading and please forgive my pool English.

Hi and welcome to devnet,

You could try running your application using gdb directly and then provoke the crash
