Quantum	fd50426dda	[client] egl: scale UI elements on high DPI displays ... This is done by actually rendering the text at high DPI.	2021-02-21 19:06:53 +11:00
Quantum	b45f7a6733	[client] egl: fix race condition in help overlay ... egl_help_set_text and egl_help_render were both accessing bmp->help from different threads. This creates a race condition in which if the help text is quickly toggled on and off, it stays on. This has been fixed with an atomic exchange.	2021-02-21 10:31:48 +11:00
Quantum	2993f7ae7d	[client] egl: create 24-bit colour context ... This should prevent the looking-glass-client window from having an alpha channel. On Wayland, the alpha channel is used to compose the window onto the desktop, so the wallpaper would bleed through unless set to complete opaque. We worked around this by using constant alpha for rendering, but it was not sustainable. Instead, we should just ask for 24-bit context.	2021-02-21 10:31:48 +11:00
Quantum	5ac53362a3	[client] renderer/egl: implement support for rendering help text ... The help text is rendered in the bottom left corner on a semi-transparent background, very similar to how the FPS text is rendered.	2021-02-21 10:31:48 +11:00
