Disable Hardware Acceleration Pegs CPU For Flash Sites

more options

We have the problem where we need to disable hardware acceleration because of disappearing graphics and text in a tab that is not the initial tab. Disabling acceleration solves the problem, so no problem, sort of.

The problem now is that Flash sites consume a lot of CPU, like 80%. Some Flash sites are worse than others but the bad ones typically end up being a game site and become so slow as to be unusable. Forge of Empires is a good example, Elvenar is pretty bad also.

All this since the Quantum release.

My system is a well equipped laptop, Win 10, latest Firefox, latest Flash, latest MS patches, no add-ons except for Flash.

I guess I am making a statement instead of asking a question, I assume there is no resolution as yet and some future release will correct the issue. Sort of wondering if others have observed this behavior and what you think about it.

Chosen solution

I read about the Cleartype thing, thought the recommendation was to turn it off, must have misunderstood. In any case 59.0.2 is running already, enabled Cleartype and it is working fine.

Thanks for the prompt response.

Please update to 59.0.2 as the issue as been resolved. https://support.mozilla.org/en-US/kb/update-firefox-latest-version This only happened on systems that had not turned on Cleartype Font. Open System and search from the bar Cleartype font and run the quick brown fox jumped......

Please let us know if this solved your issue or if need further assistance.
