I have had this issue, and one where the beam is invisible. Only been an issue when using the medic auto heal feature. However if I turn that off and hold left mouse to use the beam then I have no problems ... ?

I made a script soon after release that heals all the time unless you hold down mouse1. The difference to the continue healing option is that you have to press the button to release the beam rather than to attach it. I've been sticking with it ever since and never encountered this problem despite the fact that I've played medic a decent amount. There is a risk that you will unintentionally autofire after spawn/class change but it can be tweaked away if you know what your're doing. Let me know if something is unclear and I'll do my best to explain. alias "medic" "bind e mslot1; bind f mslot3; bind q mslot2; " alias "plus_auto_attack" "+attack; bind MOUSE1 +neg_attack" alias "minus_auto_attack" "-attack; bind MOUSE1 +attack" alias "+neg_attack" "-attack" alias "-neg_attack" "+attack" alias "mslot1" "minus_auto_attack; xslot1" alias "mslot2" "xslot2; plus_auto_attack" alias "mslot3" "minus_auto_attack; xslot3;" alias "xslot1" "slot1; r_drawviewmodel 0; cl_crosshair_red 0; cl_crosshair_green 255; cl_crosshair_blue 0" alias "xslot2" "slot2; r_drawviewmodel 0; cl_crosshair_red 255; cl_crosshair_green 0; cl_crosshair_blue 255" alias "xslot3" "slot3; r_drawviewmodel 1; cl_crosshair_red 0; cl_crosshair_green 255; cl_crosshair_blue 0" (Xslots are just slots with modification, they are not necessary for the operation of the script. They could just as well be replaced with slot1, 2 and 3. The healgun is located in slot2.)
