We don't want to encourage craziness of people making the client suid to
bypass permission issues on the shm file.
Note: I see no evidence of this happening in the wild, but let's be
proactive.
We now give ImGui the true logical size of the window and tell it to scale
the framebuffer. To fix the blurry fonts, we continue to load fonts at the
scale necessary for the DPI and use FontGlobalScale to shrink the fonts back
to the logical size. The font rectangle is then expanded by the framebuffer
scaling, resulting in good text rendering.
This method has the advantage of not messing up the sizes of resizable
overlays when moving across monitors.
The default of [0, 50] makes sense for FPS/UPS graphs, but does not for
things like the import graph. The latter should not take more than 5 ms
for sure.
This commit allows the min/max y-axis value to be specified when registering
the graph.
Now that we are drawing with damage rects, when the window is hidden and
then exposed the window may not get fully redrawn. This provides
`app_invalidateWindow` for the display server backend to call when the
screen needs a full redraw.
When a new client connects to our session the host will repeat the last
valid frame for the new client. This change will detect this and skip
the duplicated frame.
While the renderer can internally track this it would be better to
simply provide this information to the renderer directly so it can make
better decisions on how best to update the screen.
If the guest is not sending frames at a constant rate, the minimum FPS
timeout may expire drawing an additional frame. This change calculates
the average ups frame time over the past 100ms and adds this to the
timeout value allowing this value to be dynamic.
The accumulated time is not the best way to do this as the timer
function callback may not be exactly every 1000ms, by using the
monotonic clock we will get more accurate results.
The renderer may take time to process the cursor update due to various
internal factors, as such it's best we copy the data and mark the
message as done ASAP. This prevents the host from filling up the queue
as easily when a high dpi mouse is in use.
People often miss the warnings about invalid arguments in their command
line, this last minute patch attempts to address this by making
warnings, errors, fixme's and fatal errors stand out if stdout is a TTY.
A resolution switch could cause the renderer state to become invalid as
the texture format may change while it's being rendered. This fixes this
by adding a lock around the format change and render calls to the
renderer.
This adds a new method to the display server interface to allow the
application to notify the ds when there is a guest cursor position
update along with the translated local guest cursor position. This makes
it possible for the display server to keep the local cursor position in
sync with the guest cursor so that window leave events can be detected
when the cursor would move into an overlapping window.
Wayland currently just has a stub for this, and the X11 implementation
still needs some minor tweaking.
This is enabled on default. Specify wayland:warpSupport=no to disable it,
which may be useful on certain compositors that do not warp when the
pointer is confined.
This commit adds a new option, win:autoScreensaver, which when set to yes,
automatically disables the screensaver when requested by an application
running in the guest, and enables it when the application no longer wants
it disabled.
This is useful when doing media playback in the guest.
Before, if you want to see the FPS, you need to close the client and
restart it with the -k switch to see the FPS. This is annoying.
This PR introduces a new keybind, ScrollLock+D, which, when pressed,
toggles the display of the FPS.
This is implemented for both EGL and OpenGL backends.
