opens an invisible window, Can escape window, but TD frozen

if I change DPI scale is set to “Native the problem is gone”

Hey @Achim - thanks for the report.

I gave it a try and cannot reproduce it here.

However, the same screen setup but 1080GTX and Driver is at 461.40.

I’m gonna ask one of our developer with a Quadro to give it a try.

Meanwhile - can you update your drivers to R460 U3 (461.40) and give it another try?
Also, what is your DPI scaling ratio?

Thanks,
Michel

Will try that driver tmr

The 4K screen is at 150 %. One additional info: i did set the 10 Bit env var. maybe that’s relevant

I can confirm that this only happens if TOUCH_10_BIT_COLOR is set

The driver upgrade doesn’t fix it

Thanks for the extra information. I was able to reproduce some of the issues on my RTX4000 card when I enabled the 10 bit variable. We’ll take a further look into it.

We think the issue is because DPI scaling results in the window having a 16K+ width, it’s hitting a HW limit on the GPU.
