Public bug reported:
I have a problem in which the screen will behave as if I pulled the HDMI
or turned the computer off (no source) for a few seconds until the
screen comes back on again. This happens a lot when I open a new window,
moves the mouse after it has been still for a while or I open a new
window or move the current window.
I can watch a whole movie without this problem but as soon as I pause or
touch the controls of VLC or move the mouse the problem reocurr. It
seems to be after a certain idle period most of the time, but not
always. Sometimes it happens many times in a row.
The setup is my home built media PC with intel integrated graphics
(i5-9400) connected to a philips 55" TV (55POS901F) through a Pioneer AV
receiver.
I have tried probably every possible resolution and screen update
frequency and the problem is still there.
