Description Keith Hammond 2016-08-29 13:28:09 UTC

When launching KDevelop from the launcher or from the terminal without root privilege I get an unresponsive window that doesn't re-paint (or at least visibly).

Reproducible: Always

Steps to Reproduce:
1. `sudo apt install kdevelop`
2. `kdevelop`

Actual Results:  
KDevelop shows correctly but no interaction is possible. When trying to quit with the window manager controls it will be unrespossive and eventually will get a request to terminate the application.

Expected Results:  
KDevelop should open normally.

I am running KDE Neon User Edition w/ oibaf ppa and kernel 4.7

Description:    KDE neon User Edition 5.7

After running for a few seconds I get output like this every time:

Comment 3 Kevin Funk 2016-08-29 17:49:22 UTC

Please try to run KDevelop with:
  KDEV_DISABLE_WELCOMEPAGE=1 kdevelop

Please report back if that works for you.

Looks related to this: https://phabricator.kde.org/D2581

Comment 4 Keith Hammond 2016-08-29 18:35:01 UTC

That fixes it. Thanks for the quick fix.

Comment 5 Kevin Funk 2016-08-29 19:43:14 UTC

This is just a work-around, this will be fixed in 5.0.1
