Danne, can you confirm that the sluggish LCD output (looks like 2 fps) is caused by Global draw and/or mlv_lite.
It does not happen on the crop_rec experiments download as well as "builds" download. My guess is manually defined fps timers in code luckily fix it "somehow".
playing with resolution extention i need to modify fps timers - either via adtg gui or manually in fps-engio.c.
Strange thing happens now when in video mode: Global draw in conjunction with mlv_lite causes it. No sub-options causing it - but main Global Draw ON, all modes. If you disable "RAW video" then it will not be "sluggish". On the other side. If you leave "RAW video" "ON" and disable "Global draw" it will not happen, too. Could be some edmac issue or whatever. We were just in luck nobody noticing it due to manually defined timer values. Now in need to change them the issue appears.
How to confirm:
Compile 100D_merge_fw101 branch and replace 100D timers in fps-engio.c. Code below sets both timers back to its original timers by also uncommenting timer B values.:
#elif defined(CONFIG_100D)
#define TG_FREQ_BASE 32000000
#define FPS_TIMER_A_MIN (fps_timer_a_orig)
// no need to cause confusions as recording speed cannot handle such high fps in crop mode
// (ZOOM || MV1080CROP ? 1288 : 1970)) <-- these are ok while not recording.
// Hybrid CMOS AF II uses 60fps by default in LV/MV for the camera display
// to achieve a "snappy" autofocus by doubling the fps
// MV720 is not LV so we need to extend the definition for the LCD.
// #define FPS_TIMER_B_MIN (ZOOM || MV1080CROP ? 1288 : MV720 || (lv && lv_dispsize==1 && !is_movie_mode()) ? 990 : 1970)
#elif defined(CONFIG_500D)
....
....
Next enable Global draw as well as RAW video and just press zoom X5 and the LCD output will be sluggish (kind of 2fps). It will also happen after focus confirmation. There's some overlay, too. I see hundreds f focus dots on the LCD. I don't remember acting the cam like this once beginning to port ML and even recently. Could be a commit in the repo in the last 6 months or so. I must admit I didn't use the cam for a long time.
Now go figure how to solve this before continuing with anything else. Any idea what to look at @a1ex? Edmac channels?
