Magic does not seem to work well with OpenGL on Ubuntu 22.04, the layer icons are distorted 😞

@Philipp Gühring: This is a video card issue (long story involving a security flaw in old nVidia cards). It can be worked around by using cairo to draw the icons. Reconfigure using

--enable-cairo-offscreen

and then recompile (make sure to do

make clean

first).

Strange, I have an Intel chipset CometLake-U GT2 with UHD Graphics, not Nvidia... But I will give it a try

If I remember the history correctly, the original issue was caused by an nVidia chipset, but the ultimate result was that everybody disabled off-screen rendering in all OpenGL implementations.
