Lockup using daemon mode #85

Open ortango opened 5 months ago

ortango commented 5 months ago

Occasionally, sometimes frequently mlterm will lock up when I spawn a terminal with mlclient (using xft type engine).

xft_font_open, ui_font_ft.c:357 returns xerror and mlterm gets stuck in error_handler. The following backtrace is missing symbols, but has a value for request_code that is not 0. Most of the traces were getting a 0 value, I'm not sure why. I can add a backtrace with full symbols.

Thanks. I'm sorry but I can't reproduce it in my environment. 1) Will you show me your ~/.mlterm/main and ~/.mlterm/aafont ? 2) Does this problem happen if you remove files in ~/.mlterm ?

Hey there, thanks for taking the time to check this out.

The same issue happens without a user mlterm configuration. I've included the main and aafont configs below anyway.

main

inner_border = 12
termtype = rxvt
fontsize = 14
type_engine = cairo
use_scrollbar = false
fg_color = #c0b18b
bg_color = #1f1f1f
cursor_fg_color = #1f1f1f
cursor_bg_color = #c0b18b

aafont

DEFAULT=GohuFont Powerline
ISCII_ASSAMESE  = AS-TTDurga 26
ISCII_BENGALI   = BN-TTDurga 26
ISCII_GUJARATI  = GJ-TTAvantika 21
ISCII_HINDI = DV-TTYogesh 23
ISCII_KANNADA   = KN-TTUma 25
ISCII_MALAYALAM = ML-TTKarthika 23
ISCII_ORIYA = OR-TTSarala 26
ISCII_PUNJABI   = PN-TTAmar 30
ISCII_TELUGU    = TL-TTHemalatha 25
