Do you use compton? I had similar issues with VTE (xterm) and the issue appears only when compton is active. This started to happen after August 2 so p20160704 is not affected but p20160803 and later yes. See [1] for details. The fix is to build compton from git, but it brings new issues (for me it was Firefox). I think it may happen on other compositors. [1] https://github.com/chjj/compton/issues/376 1. NOT security bug, this is the way x86 graphics hardware works (with all current drivers) 2. disable all compositing as requested and try again Finally found the time to get back to this issue. Yes I am running compton. But I can't find a way to make it work. The suggested cmdline-invocation didn't help. Changing backends didn't help, xr_glx_hybrid made things worse - windows including the desktop just disappeared. I used compton mostly to get a tearfree desktop, because non-composited tearing is even worse than what I see with newer intel-driver... I hope glamor will finally fix this issue for me. I gave it a try and it seems to do a good job. xorg-server-1.19 is said to even further improve it. |
