All, I have a number of virtualbox guests I run from my Arch host and have for a number of years. Since update to Linux 4.20 and update to Virtualbox 6.0, the Windows7 guests (with default guest additions graphics driver settings) shows a very notable slowdown in graphics performance when accessed over rdesktop. The guests are run headless.
From 4.x through 5.2.22, there was no problem with Win7 guest usability when run in this configuration. Starting with 6.0.0, the Win7 guests are almost unusable. Moving a window leaves noticeable artifacts on the desktop which you can clearly see the WM_PAINT redraw and removal of the prior window positions throughout the window move. Using cmd.exe and simply doing a DIR on a directory with a hundred files or so, is painfully slow, printing no more than 10 lines per-second, taking many seconds just to complete the listing. Very much like watching a DOT-Matrix printer print. In all releases prior to 6.0.0, there was no problem here. Additionally, the Archlinux and OpenSuSE guest run in the same headless config, show no similar problem listing directory contents in an xterm. I'm out of answers on this one. Has anyone seen anything similar and moreover has anyone found a fix? -- David C.
