[PyMOL] Two issues with the draw command with current pymol version 3.1.5.1

[Norbert S. <st...@bb...>]

Dear all,

I would like to report two issues with the current pymol version 
3.1.5.1, which were present as well already in 3.1.4. The two problems 
were not present in my previous installation of version 3.0.2. The two 
problems are observed on a windows 11 notebook and on a linux computer. 
The issues appear with different images, the following is a simple test 
case:

reinitialize
viewport 800,600
pseudoatom my_atom, pos=[1.0, 2.0, 3.0]
show spheres, my_atom
set label_position, [0.0, 0.0, 2.0]
label my_atom, "my_atom"
set label_size, 30
set label_color, black
zoom my_atom

(1) draw command results in smaller label size

If you use the draw command after pasting the commands above, the label 
is plotted much smaller. When using the ray command, the label size is 
fine. Using pymol 3.0.2 draw and ray commands result in approximately 
the same label size as in the interactive working window.

(2) draw command in conjunction with "set antialias_shader, 2" renders 
only part of the image

If you "set antialias_shader, 2" and use the draw command, only part of 
the image is rendered. This may seem like a special option, but it is 
part of the Menu option "Display, Quality, Maximum Quality", which I 
frequently use. The ray command is not affected. "set antialias_shader, 
0" (the default) or "set antialias_shader, 1" cause no problem.

Best regards,

Norbert
