Hi,

After some experiments with the refresh rate, I couldn't solve the problem. But I have found a workaround by disabling both gauges in the Virtual cockpit. Strang, but it works:

[VCockpit07]
size_mm=1000,1000
pixel_size=512,512
texture=$cs767_15_T
background_color=0,0,0
;gauge00=Captain_Sim.y763.sys!eicas_u,        0,   0,1000, 965, 5

[VCockpit08]
size_mm=1000,1000
pixel_size=512,512
texture=$cs767_16_T
background_color=0,0,0
;gauge00=Captain_Sim.y763.sys!eicas_l,        0,   0,1000, 965, 5

Kind regards,
Kees
