Public bug reported:
Whenever I operate a mouse and simultaneously use the touchscreen, the whole
user interface freezes:
- no mouse operation possible
- no keyboard operation
- video playback halts
- fan goes up
The duration of this freeze seems to be related to the amount of input,
I'm generating simultaneously with the touchscreen and the mouse.
After a few seconds:
- mouse operates normally again
- all missing keyboard input is showing up immediately wherever I had the focus
- video skips the frozen seconds and continues
- fan returns to normal operation
It doesn't matter whether I use a bluetooth mouse or the touchpad. Note
that this does not happen when simultaneously operating mouse and
touchpad.
It seems to me that xorg is running into some kind of loop, possibly
trying to make sense of contradictory input from mouse/touchpad and
touchscreen.
Yes, this is an unlikely situation, but it happens most of the time when
someone else is trying to show me something on the screen and
accidentally touches it, while I'm doing something with the mouse.
