Bug Description
After a regular update of my LTS during the last week, the screen has started showing corruption. For instance, when I maximise a window, the screen flickers for up to a second with an overlay of black dashes and stripes, sometimes in a chevron pattern or just horizontal black dashes covering the whole screen, especially on an external display.
It does not show up in a screen capture.

Christopher Barrington-Leigh, thank you for reporting this and helping make Ubuntu better. As per http:// support. lenovo. com/us/ en/products/ laptops- and-netbooks/ thinkpad- x-series- tablet- laptops/ thinkpad- x230-tablet an update to your computer's buggy and outdated BIOS is available (2.60). If you update to this following https:/ /help.ubuntu. com/community/ BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see https:/ /help.ubuntu. com/community/ ReportingBugs# Bug_reporting_ etiquette .
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.
Once the BIOS is updated, and the information above is provided, then please mark this report Status New.
Thank you for your understanding.
