qt: don't reinitialise RenderControl OpenGL context on expose in X11 compositor. (!1341) · Merge requests · VideoLAN / VLC

Pierre Lamot requested to merge chub/vlc:qt/dont-reinitialize-gl-context into master Feb 03, 2022

re-initialising the context was causing severe performance degradation (hangs, CPU consumption & RAM) in the snap version (at least) when KDE QuickStyle was used.

maybe related to #26392, I only reproduced this with snap so far.
