Hi, I noticed that on my computer too a few months back. I had the same problem with Audacity and Kicad (both wxwidgets apps).
For what I understand, this has been tracked down to a bug in the Intel driver in conjunction with a Xorg bug when using unaccelerated graphics. But I may be wrong. So first, double check you are using hardware acceleration. I thought I was and I wasn't for months :).
