Intel UHD 630 - Bitmap fonts rendering artefacts

ABohr — Tue, 06 Nov 2018 14:24:27 GMT

System Used: DELL Precision 7530

CPU SKU: i7-8750H

GPU SKU: UHD 630

Graphics Driver Version: 25.20.100.6373

GOP/VBIOS Version: 9.0.1074

Operating System: Windows 10 Pro x64

OS Version: 10.0.17134

I notice strange bug when displaying raster (bitmap) system fonts in applications. When used, there is visible character shadow repeating through the whole line regardless of application window boundaries. I have ruled out screen issues as this is visible even when I take a screenshot. TrueType fonts are unaffected by this. By the time of writing all OS, BIOS, Video drivers are up to date. And Windows were freshly installed.

Steps to Reproduce:

1. Set dark non-solid desktop background. Place icons on the desktop.

2. Open Notepad

3. Use fixedsys.fon or terminal.fon and check 'Word Wrap'

4. Position Notepad window so borders are near desktop icons (icons on the right side of window)

5. type letter 'x' continuously until couple of lines filled

On Notepad scroll bar and desktop icons ghostly visible 'x's are appearing.

abohr: Thank you very much for joining the Intel® communities.

We recommend to install the graphics driver provided by Dell, that driver was customized by them to work with your specific platform, please try version 24.20.100.6287 ,A05:

I can see there are graphics drivers available for Nvidia and AMD, you can also try to install those drivers:

Could you please provide a screen shot of the issue?

Thank you for your recommendations. Unfortunately, problem still persists. I have done some more troubleshooting, and on deeper examination, it is possible the issue might be the result of screen processing after all, not graphic card / drivers. I have contacted Dell to see if they have any idea about that.

abohr: You are very welcome. We are sorry to hear the issue persists. Perfect, in this case that will be the next thing to do, Dell might be able to replicate the issue and provide further suggestions for this scenario.
