Terminal is unusably slow in 1.26.0 and 1.26.1 (--ignore-gpu-blacklist not help)

[fessmage]

Issue Type: Performance Issue

After update vscode to 1.26.1 from 1.25.1 i experienced problem with unusably slow rendering. Switching renderertype from 'canvas' to 'dom' doesn't help me, neither --ignore-gpu-blacklist option.

I checked problem and seen it in 1.26.0 too.

I am reverted vscode version from 1.26.1 to 1.25.1 because of it, in 1.25.1 terminal with renderertype 'canvas' works fast again. I stay with this version until some fix.

This problem looks like that comment -
#56517 (comment), but i starting new issue because ignoring gpu blacklist doesn't help me, only old version.
