I have Ubuntu 14.04
When I use Geany or PyCharm IDEs the system will lock up completely (usually after some fast scrolling the text window e.g. using the mouse wheel)
The same effect is not observed using Kate. I can get a freeze within a minute using Geany or PyCharm, but I can use Kate for weeks with no problem
Can someone please give me a hint where to look to solve this (maybe Geany and PyCharm use java (just a guess) and this might be significant)
using PyCharm I also see this message
IBus prior to 1.5.11 may cause input problem. See IDEA-78860 for details.
I'm using 1.5.5. Might this be relevant?
[RE-EDIT 3 June 2016] I have tried PyCharm on a 'clean' (new) Ubuntu 14.04 set up and it works perfectly. So clearly there is some conflict here. can someone suggest what it might be?
