DELL xps 13 9350 notebook has bad display

I tested blender official 2.79, blender-2.79-e8daf2e-win64.zip( 116M, Mon Oct 30 03:13:48 2017) and blender-2.80-bed3cbd-win64-vc14.zip( 115M, Mon Oct 30 04:55:04 2017) on DELL xps 13 9350 notebook( win10 64 bits, Intel HD Graphics 520,1920*1080 desktop resolution. all drivers have been updated using dell update)

for the user preference, you can find that there is no tab( interface, edit, … system) shown. I have to use ctrl+tab to switch tabs


Moved from “General Forums > Blender and CG Discussions” to “Support > Technical Support”

then I want to change display scale, but I found that cursor has bad location. you can read that when I put the cursor in Line Width, it is actually display scale



when display scale is 1.5, the bottom part of tabs can be seen


any hints to solve this? Thanks

I can’t reproduce this behavior. Have you tried scrolling your mouse wheel? Perhaps those pieces are there, but you’re somehow scrolled a bit south in that window.

Do those buttons at the top appear when you view User Preferences from within another area of Blender? (that is, instead of using File > User Preferences, change one of the editor areas–like the 3D View–to User Preferences)

Seems like it is this Intel driver bug: https://developer.blender.org/T51521
Things work better with older drivers with Intel.

thanks
Intel HD 520 driver 21.20.16.4534 2016/10/7 works
but 21.20.16.4664 2017/4/21 and 21.20.16.4821 2017/10/2 does not
