I put my current workaround for this issue on the Linux page in CamBam's main documentation page:
https://cambamcnc.com/ref/ref.linux#cmt_link202Pasting the relevant part here:
Use a xpra session to run CamBam and connect to it locally.
The "run_scaled" script at
https://github.com/kaueraal/run_scaled wraps xpra nicely.
The following worked for me:
(cd ~/CamBam1.0/ && wget https://raw.githubusercontent.com/kaueraal/run_scaled/master/run_scaled)
sudo chmod +x ~/CamBam1.0/run_scaled
sudo apt install xvfb xpra x11-xserver-utilsStart CamBam with something like:
~/CamBam1.0/run_scaled --opengl=no --scale=1 ~/CamBam1.0/cambam.shor
~/CamBam1.0/run_scaled --scale=1 ~/CamBam1.0/cambam.sh(Use which ever looks nicer on your system.)
Note that you pass "--scale=1" to the script so it launches CamBam at the default size.
Now you can scale the whole window using the little green "xpra" icon in the top toolbar.
