Missing letters

[iva]

Hey guys,

I have the most bizzare problem which will, if nothing else, make you laugh.

some of my letters on the screen are missing. I am attaching a screenshot.

The strings get logged properly, so this is really just a rendering issue. The machine is Windows 10. The graphics card is Intel HD Graphics 530.

Help.

That is interesting. You could try updating the graphics drivers to see if it makes a difference. What version of Vizard do you have and could you post the vizinfo code that was run for the screenshot?

The driver is up to date. This is my code:

def showbuttons():
global buttons
global next
global info
global d1
global task
global logbutton
global buttontick
global lbutton
logbutton= radios[task][d[task]][0]
info = vizinfo.add( 'Where do you\n have to go?' )
info.bgcolor(viz.BLACK,1.0)
info.translate( [.98, .905] )
buttons=[]
for i in range(len(radios[task][d[task]])):
#if radios[task][d[task]][i]!="none":
buttons.append(info.add( viz.RADIO, task*10+d[task], radios[task][d[task]][i]))
#next=info.add(viz.BUTTON_LABEL, "Next")
lbutton.visible(1)
buttontick=viz.tick()
viz.callback(viz.BUTTON_EVENT,butts)

It is a bit messy out of the context unfortunately, but I don't do anything but append buttons to the vizinfo box. Also, the labels of the buttons get logged properly, so letters don't get lost in the process, it is just the rendering issue. Additionally, it works on my dev machine, just not on the lab machine... where it is important:)

I am using Vizard 4.09.0016.

Do you have the same issue running the following code?

import viz
import vizinfo

viz.go()

info = vizinfo.add( 'Where do you\n have to go?' )
info.bgcolor(viz.BLACK,1.0)
info.translate( [.98, .905] )
button1 = info.add( viz.RADIO,0,'straight')
button2 = info.add( viz.RADIO,0,'left')
button3 = info.add( viz.RADIO,0,'up')
button4 = info.add( viz.RADIO,0,'down')
button5 = info.add( viz.RADIO,0,'right')
button6 = info.add( viz.BUTTON_LABEL, 'Next')

Since the same code works on another machine it seems GPU/driver related. Try changing the performance settings mentioned in this article (http://www.howtogeek.com/245592/how-to-improve-gaming-performance-with-intel-hd-graphics-chips/). You could also try rolling back the drivers to see if that makes a difference.
