When I keep a key pressed, and let X autorepeats to kick in, the terminal window is not refreshed. The application as if it's receiving no keypress, but when the key is released, a bunch of keypresses are added at once.
This is particularly unconvenient with the arrow keys or pgdn/pgup. This means we cannot keep these keys pressed to scan through a text file, or edit a command line.
I can more or less fix the problem by reducing the autorepeat rate:
xset r rate 500 15
With rate = 20, it starts to stutter. At default rate = 31, it mutes.
This is on VcXsrv 1.19.2.0, on Windows 7 (client Ubuntu 16.04 running in VBox), connected in Multi-Window mode.
Note that the issue does not show up in XMing (version 7.7.0.3, paid version).
For info, I tried a few things:
Sometimes I get the error:
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
yes ,vcxsrv libGL error:
