Decompilation window not updated on ILSpy version 7.2.0.0.rc / Linux x64

[speters]

Thx for this great tool!

With the current ILSpy version 7.2.0.0.rc build for Linux x64
ILSpy stops updating the decompilation window.

I can not exactly reproduce it, but it happens on every session after a while.

Additionally, the screen capture shows the font config problem (maybe related to #84). Close button is unresponsive, but config window can be closed by clicking (x) in upper right window decoration.

Setup is Arch Linux running KDE Plasma.
