Reproduction steps: Run a scan, open Tasks/Reports, maximize window on high resolution screen (2560x1600 px at 115% here).
Actual result: Output is not GPU accelerated, high CPU load with one thread/core being maxed out, high lag for input commands (mouse, keyboard)
Expected Result: Low CPU load, smooth operation
Animated GIF: Reports CPU load + lag (4.16% = 1 out of 24 logical cores maxed out)
Tasks CPU load (4.16% = 1 out of 24 logical cores maxed out)
