Windows 10 21H1 Graphical Glitches in Menus

#1

Post by JasonT »

Hi All,

Sharpcap 4.0.7995.0 (64 bit)
Windows 10 (21H1)

I am getting weird graphical glitches in the menus of Sharpcap (blank buttons, font zooming etc.)
I figured this might be a windows video driver issue, so I ended up doing a full clean windows 10 install (21H1 version) and verifying I had all the latest drivers.

Anyway, the problem persists.

For the log I am clicking OK on the tip, selecting the deep sky test camera and taking a snapshot

Any Windows gurus out there can help?

Hi,

all of the things that are glitching are drawn using a particular UI technology called WPF. That technology can sometimes have problems with graphics drivers issues or when using remote access software, so there is a command line option for SharpCap that forces the rendering of those things to be done using software rather than graphics driver hardware, which might work around the issue.

From the command line, run SharpCap with the '/softwarerendering' option - ie something like

Code: Select all

"c:\Program Files\SharpCap 4.0 (64 bit)\sharpcap.exe" /softwarerendering
If that fixes the glitches then it is both a workaround and also an indication that graphics card issues may be behind the problem. What graphics card are you using btw?

cheers,

Robin

Hi Robin,

yes that switch works :)

I am almost sure the behaviour started wit a Windows update at some point, but since I've done a reinstall I can't go back now, I guess theres a chance it will get fixed in another one :roll:

The graphics card is Intel UHD 630 in a gaming laptop I am repurposing for astro fun.

Thanks for your help

Hi,

Glad the software switch worked :)

I just let my PC update to 21H1 and have no glitches since the update (NVidia graphics card). Not sure if I have anything around here that has Intel graphics - if I do I will try to test it out, but I strongly suspect the graphics drivers :(

cheers,

Robin

Hi Robin,

a further update - I had issues in NINA as well, and over on their discord I was directed to this microsoft article:

https://docs.microsoft.com/en-us/dotnet ... esktop-4.8

so I have disabled hardware rendering globally and I can now run NINA and Sharpcap (without the switch) without the corruption.

Hopefully the driver will get fixed at some point..... :shock:
