Just tried upgrading my Xubuntu 19.10 desktop to 20.04 and I'm now getting the same staircase effect. Video card is an AMD Radeon RX 5700 XT which is connected with a DisplayPort -> DVI-D cable to an ancient LG W2252TQ monitor with a resolution of, yes, 1680x1050. It is the only monitor connected.
Just thought I'd share. Rolling back to 19.10 now. I'll try again with the point release. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxcb in Ubuntu. https://bugs.launchpad.net/bugs/1873895 Title: Regression: block staircase display with side-by-side monitors of different pixel widths To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1873895/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
