Bug ID: 104198
Summary: [i915] [device 591b] Xorg with framebuffer driver
corrupt text / font
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Intel

i have a Thinkpad T470-P which is equipped with Intel HD graphics 630
00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04)
I have a big issue with text getting corrupt, complete rows get messed up,
most problem in Qtcreator but also noticed it in Konsole.
kernel module loaded for the graphics card is i915.
Xorg is default using fbdevhw when booting stock kernel and with kernel
4.14.4-041404 it is using modesetting driver with submodule fb.
I tried changing font, changing font settings like anti aliasing, sub pixel
rendering e.t.c. without any luck.
I tried upgrading the kernel to 4.14.4-041404, upgrading the bios.
Misc info:
I have installed Kubuntu 17.04, It works almost fine out of the box.
The size of everything on the screen was very small so i scaled it to 1.1 in
KDE settings. Increased fonts sizes and forced DPI to 120.
I tried upgrading graphics drivers with intel graphics update tool 2.06:
https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.6
But it caused waking up from suspend to not work, seems the screen is not
enabled, also the adjusting of the backlight stoped working.
Thank you.
