Clicking on View -> Adjust Window size does nothing. I need manually resize guest window each time. Which is quite annoying, plus results in desktop environment cresh some times (but thats another story).
I have tried to set File -> Preferences -> Display to Automatic, Hint and none. I have tried to check/uncheck "View -> Auto resize Guest display". No effect. Also. If "Auto resize Guest display" is not checked, after window size is reduced, viewport size is not changed on window resize. Even if I stretch window, guest viewport size remains the same and just gray window border is increased.
Any ideas how to prevent window resizing on keypress.
I see the following entries in the VM log, when window is resized(02:57:05).
