Display content currentness validation

A system comprising:

• a memory device;
• a processing device, coupled to the memory;
• and
• a plurality of display devices, coupled to the processing device, wherein the processing device is to:
• access, by a validation module, one or more memories associated with one or more rendering modules executed by one or more graphics processing units of the system to verify that the one or more rendering modules render up to date content on each of the plurality of display devices;
• retrieve, from the one or more memories by the validation module, a plurality of timestamps, wherein each of the plurality of timestamps is embedded in corresponding content rendered by the one or more rendering modules on each of the plurality of display devices;
• compare, by the validation module, each of the plurality of timestamps to a current time of the system;
• and
• responsive to determining that at least one of the plurality of timestamps does not correspond to the current time of the system, determine that the corresponding content rendered by the one or more rendering modules on at least one of the plurality of display devices is outdated.

A non-transitory device-readable medium storing instructions that, when executed by a processing device associated with a computer system, cause the processing device to perform operations comprising:

• accessing, by a validation module executed by the processing device, memory associated with a rendering module executed by a graphics processing unit of the computer system to verify that the rendering module renders up to date content on a display device of the computer system;
• retrieving, from the memory by the validation module, a timestamp embedded in content rendered by the rendering module on the display device;
• comparing, by the validation module, the timestamp to a current time of the computer system;
• and
• responsive to determining that the timestamp does not correspond to the current time of the computer system, determining that the content rendered by the rendering module on the display device is outdated.
