Thanks - I had already tried chanhing display resolution and various themes, but the artefact remained. I've had the machine for a year and not seen anything like it with other applications. However, I took your advice and went to the Dell site to get the latest firmware and drivers. Two reboots later - it's fixed! Thanks for your help.

OK - hopefully this link will do it http://postimg.org/image/kwdqb1s8h/ Interestingly, I get a hint of similar behaviour when browsing the website - see the "Follow this forum" button. http://postimg.org/image/6js0cwxrt/ Seems like my machine doesn't like the bitmaps

I've recently installed version 1.4.106 beta on my Dell XPS 12 with 1920 x 1080 display. I get the weird display corruption show below. Diagonal crosses are a recurring theme. I can't read pop-ups, and column headers are often unreadable too. Thanks for looking. Actually, I don't seem to be able to post the image - is there a way to attach a jpg file so you can see what I'm talking about?
