Hello, am repeat user.
Whonix-Workstation with KDE on qemu/kvm crashes randomly but regularly on average twice every 12 hours. It logs out and kills all DE processes, losing all data.
I have experienced this on 2 different hosts ever since Debian Jessie, for months on end, and a workstation reinstall.
In addition, copy-pasting from host to guest (with spice) at random times will fail and completely lock up the KDE window of the target program. It often but not always comes before a full KDE crash.
I added the qxl surfaces hack.
I have never experienced this with any other guest OS/Desktop environment. Only Whonix with KDE.
I normally don't complain about choice of DE but in this case it is so bad that the workstation is unusable for any serious purpose. I am writing this is Kwrite and saving every 5 seconds because I am afraid it will crash any moment.
I know it's the author's choice but I feel after this prolonged experience with KDE in a VM that a lightweight desktop such as LXDE or XFCE would be infinitely more appropriate (I am not a fan of the Qubes's project choices either), though I am not a fan of any DE.
I would settle for a fix to this crashing if someone knows of one. I will have no choice but to make a custom workstation which I would rather not. Normally I prefer to adapt to whatever's given. It takes a lot to get me to this point...
